+## Getting Started:
+To run umbraco, we first need to initialize the client git submodule:
+* Execute `git submodule update --init` to get the files into Umbraco.Web.UI.Client project
+* If you are going to work on the Backoffice, you can either go to the Umbraco.Web.UI.Client folder and check out a new branch or set it up in your IDE, which will allow you to commit to each repository simultaneously:

+* If you get a white page delete Umbraco.Cms.StaticAssets\wwwroot\umbraco folder and run `npm ci && npm run build:for:cms` inside Umbraco.Web.UI.Client folder to clear out any leftover files from older versions.
+
+### Latest version
+* If you want to get the latest changes from the client repository, run `git submodule update` again which will pull the latest main branch.

-### Familiarizing yourself with the code
+To build the front end you'll need to open the command pallet (<kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd>) and run `>Tasks: Run Task` followed by `Client Watch` and then run the `Client Build` task in the same way.
 
-Umbraco is a .NET application using C#. The solution is broken down into multiple projects. There are several class libraries. The `Umbraco.Web.UI` project is the main project that hosts the back office and login screen. This is the project you will want to run to see your changes.
-
-There are two web projects in the solution with client-side assets based on TypeScript, `Umbraco.Web.UI.Client` and `Umbraco.Web.UI.Login`.
-
-There are a few different ways to work locally when implementing features or fixing issues with the Umbraco CMS. Depending on whether you are working solely on the front-end, solely on the back-end, or somewhere in between, you may find different workflows work best for you.
-
-Here are some suggestions based on how we work on developing Umbraco at HQ.
-
-### First checkout
-
-When you first clone the source code, build the whole solution via your IDE. You can then start the `Umbraco.Web.UI` project via the IDE or the command line and should find everything across front and back-end is built and running.
+You can also run the tasks manually on the command line:
 
 ```
-cd <solution root>\src\Umbraco.Web.UI
-dotnet run --no-build
+cd src\Umbraco.Web.UI.Client
+npm i
+npm run dev
 ```
 
-When the page loads in your web browser, you can follow the installer to set up a database for debugging. When complete, you will have an empty Umbraco installation to begin working with. You may also wish to install a [starter kit][https://marketplace.umbraco.com/category/themes-&-starter-kits] to ease your debugging.
+If you just want to build the UI Client to `Umbraco.Web.UI` then instead of running `dev`, you can do: `npm run build`.
 
-### Back-end only changes
-
-If you are working on back-end only features, when switching branches or pulling down the latest from GitHub, you will find the front-end getting rebuilt periodically when you look to build the back-end changes. This can take a while and slow you down. So if for a period of time you don't care about changes in the front-end, you can disable this build step.
-
-Go to `Umbraco.Cms.StaticAssets.csproj` and comment out the following lines of MsBuild by adding a REM statement in front:
+The login screen is a different frontend build, for that one you can run it as follows:
 
 ```
-REM npm ci --no-fund --no-audit --prefer-offline
-REM npm run build:for:cms
+cd src\Umbraco.Web.UI.Login
+npm i
+npm run dev
 ```
 
-Just be careful not to include this change in your PR.
+If you just want to build the Login screen to `Umbraco.Web.UI` then instead of running `dev`, you can do: `npm run build`.
 
-### Front-end only changes
+**The initial Gulp build might take a long time - don't worry, this will be faster on subsequent runs.**
 
-Conversely, if you are working on front-end only, you want to build the back-end once and then run it. Before you do so, update the configuration in `appSettings.json` to add the following under `Umbraco:Cms:Security`:
+You might run into [Gulp quirks](#gulp-quirks).
 
-```json
-"BackOfficeHost": "http://localhost:5173",
-"AuthorizeCallbackPathName": "/oauth_complete",
-"AuthorizeCallbackLogoutPathName": "/logout",
-"AuthorizeCallbackErrorPathName": "/error",
-"BackOfficeTokenCookie": {
-  "SameSite": "None"
-}
-```
+The caching for the back office has been described as 'aggressive' so we often find it's best when making back office changes to [disable caching in the browser (check "Disable cache" on the "Network" tab of developer tools)][disable browser caching] to help you to see the changes you're making.
 
-> [!NOTE]
-> If you get stuck in a login loop, try clearing your browser cookies for localhost, and make sure that the `Umbraco:Cms:Security:BackOfficeTokenCookie:SameSite` setting is set to `None`.
-
-Then run Umbraco from the command line.
+To run the C# portion of the project, either hit <kbd>F5</kbd> to begin debugging, or manually using the command line:
 
 ```
-cd <solution root>\src\Umbraco.Web.UI
-dotnet run --no-build
+dotnet watch --project .\src\Umbraco.Web.UI\Umbraco.Web.UI.csproj
 ```
 
-In another terminal window, run the following to watch the front-end changes and launch Umbraco using the URL indicated from this task.
+**The initial C# build might take a _really_ long time (seriously, go and make a cup of coffee!) - but don't worry, this will be faster on subsequent runs.**
 
-```
-cd <solution root>\src\Umbraco.Web.UI.Client
-npm run dev:server
-```
+When the page eventually loads in your web browser, you can follow the installer to set up a database for debugging. You may also wish to install a [starter kit][starter kits] to ease your debugging.
 
-You'll find as you make changes to the front-end files, the updates will be picked up and your browser refreshed automatically.
+#### Debugging with Visual Studio
 
-> [!NOTE]
-> The caching for the back office has been described as 'aggressive' so we often find it's best when making back office changes to [disable caching in the browser (check "Disable cache" on the "Network" tab of developer tools)][disable browser caching] to help you to see the changes you're making.
+In order to build the Umbraco source code locally with Visual Studio, first make sure you have the following installed.
 
-Whilst most of the backoffice code lives in `Umbraco.Web.UI.Client`, the login screen is in a separate project. If you do any work with that you can build with:
+  * [Visual Studio 2022 v17+ with .NET 7+](https://visualstudio.microsoft.com/vs/) ([the community edition is free](https://www.visualstudio.com/thank-you-downloading-visual-studio/?sku=Community&rel=15) for you to use to contribute to Open Source projects)
+  * [Node.js v14+](https://nodejs.org/en/download/)
+  * npm v7+ (installed with Node.js)
+  * [Git command line](https://git-scm.com/download/)
 
-```
-cd <solution root>\src\Umbraco.Web.UI.Login
-npm run build
-```
+The easiest way to get started is to open `umbraco.sln` in Visual Studio.
 
-In both front-end projects, if you've refreshed your branch from the latest on GitHub you may need to update front-end dependencies.
+To build the front end, you'll first need to run `cd src\Umbraco.Web.UI.Client && npm install`  in the command line (or `cd src\Umbraco.Web.UI.Client; npm install` in PowerShell). Then find the Task Runner Explorer (View → Other Windows → Task Runner Explorer) and run the `build` task under `Gulpfile.js`. You may need to refresh the Task Runner Explorer before the tasks load.
 
-To do that, run:
+If you're working on the backoffice, you may wish to run the `dev` command instead while you're working with it, so changes are copied over to the appropriate directories and you can refresh your browser to view the results of your changes.
 
-```
-npm ci --no-fund --no-audit --prefer-offline
-```
+**The initial Gulp build might take a long time - don't worry, this will be faster on subsequent runs.**
 
-### Full-stack changes
+You might run into [Gulp quirks](#gulp-quirks).
 
-If working across both front and back-end, follow both methods and use `dotnet watch`, or re-run `dotnet run` (or `dotnet build` followed by `dotnet run --no-build`) whenever you need to update the back-end code.
+The caching for the back office has been described as 'aggressive' so we often find it's best when making back office changes to [disable caching in the browser (check "Disable cache" on the "Network" tab of developer tools)][disable browser caching] to help you to see the changes you're making.
 
-Request and response models used by the management APIs are made available client-side as generated code. If you make changes to the management API, you can re-generate the typed client code with:
+"The rest" is a C# based codebase, which is mostly ASP.NET Core MVC based. You can make changes, build them in Visual Studio, and hit <kbd>F5</kbd> to see the result.
 
-```
-cd <solution root>\src\Umbraco.Web.UI.Client
-npm run generate:server-api-dev
-```
+**The initial C# build might take a _really_ long time (seriously, go and make a cup of coffee!) - but don't worry, this will be faster on subsequent runs.**
 
-Please also update the `OpenApi.json` file held in the solution by copying and pasting the output from `/umbraco/swagger/management/swagger.json`.
+When the page eventually loads in your web browser, you can follow the installer to set up a database for debugging. You may also wish to install a [starter kit][starter kits] to ease your debugging.

-# Contribution Guidelines
-
-## Thoughts, links, and questions
-
-In the high probability that you are porting something from angular JS then here are a few helpful tips for using Lit:
-
-Here is the LIT documentation and playground: [https://lit.dev](https://lit.dev)
-
-### What is the process of contribution?
-
--   Read the [README](README.md) to learn how to get the project up and running
--   Find an issue marked as [community/up-for-grabs](https://github.com/umbraco/Umbraco.CMS.Backoffice/issues?q=is%3Aissue+is%3Aopen+label%3Acommunity%2Fup-for-grabs) - note that some are also marked [good first issue](https://github.com/umbraco/Umbraco.CMS.Backoffice/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) which indicates they are simple to get started on
--   Umbraco HQ owns the Management API on the backend, so features can be worked on in the frontend only when there is an API, or otherwise if no API is required
--   A contribution should be made in a fork of the repository
--   Once a contribution is ready, a pull request should be made to this repository and HQ will assign a reviewer
--   A pull request should always indicate what part of a feature it tries to solve, i.e. does it close the targeted issue (if any) or does the developer expect Umbraco HQ to take over
-
-## Contributing in general terms
-
-A lot of the UI has already been migrated to the new backoffice. Generally speaking, one would find a feature on the projects board, locate the UI in the old backoffice (v11 is fine), convert it to Lit components using the UI library, put the business logic into a store/service, write tests, and make a pull request.
-
-We are also very keen to receive contributions towards **documentation, unit testing, package development, accessibility, and just general testing of the UI.**
-
-## The Management API
-
-The management API is the colloquial term used to describe the new backoffice API. It is built as a .NET Web API, has a Swagger endpoint (/umbraco/swagger), and outputs an OpenAPI v3 schema, that the frontend consumes.
-
-The frontend has an API formatter that takes the OpenAPI schema file and converts it into a set of TypeScript classes and interfaces.
-
-**Current schema for API:**
-
-[https://raw.githubusercontent.com/umbraco/Umbraco-CMS/v13/dev/src/Umbraco.Cms.Api.Management/OpenApi.json](https://raw.githubusercontent.com/umbraco/Umbraco-CMS/v15/dev/src/Umbraco.Cms.Api.Management/OpenApi.json)
-
-**How to convert it:**
-
--   Run `npm run generate:server-api`
-
-## A contribution example
-
-### Example: Published Cache Status Dashboard
-
-![Published Status Dashboard](/.github/img/contributing/published-cache-status-dashboard.png)
-
-### Boilerplate (example using Lit)
-
-Links for Lit examples and documentation:
-
--   [https://lit.dev](https://lit.dev)
--   [https://lit.dev/docs/](https://lit.dev/docs/)
--   [https://lit.dev/playground/](https://lit.dev/playground/)
-
-### Functionality
-
-**HTML**
-
-The simplest approach is to copy over the HTML from the old backoffice into a new Lit element (check existing elements in the repository, e.g. if you are working with a dashboard, then check other dashboards, etc.). Once the HTML is inside the `render` method, it is often enough to simply replace `<umb-***>` elements with `<uui-***>` and replace a few of the attributes. In general, we try to build as much UI with Umbraco UI Library as possible.
-
-**Controller**
-
-The old AngularJS controllers will have to be converted into modern TypeScript and will have to use our new services and stores. We try to abstract as much away as possible, and mostly you will have to make API calls and let the rest of the system handle things like error handling and so on. In the case of this dashboard, we only have a few GET and POST requests. Looking at the new Management API, we find the PublishedCacheService, which is the new API controller to serve data to the dashboard.
-
-To make the first button work, which simply just requests a new status from the server, we must make a call to `PublishedCacheService.getPublishedCacheStatus()`. An additional thing here is to wrap that in a friendly function called `tryExecuteAndNotify`, which is something we make available to developers to automatically handle the responses coming from the server and additionally use the Notifications to notify of any errors:
-
-```typescript
-import { tryExecuteAndNotify } from '@umbraco-cms/backoffice/resources';
-import { PublishedCacheService } from '@umbraco-cms/backoffice/external/backend-api';
-
-private _getStatus() {
-  const { data: status } = await tryExecuteAndNotify(this, PublishedCacheService.getPublishedCacheStatus());
-
-  if (status) {
-    // we now have the status
-    console.log(status);
-  }
-}
-```
-
-### State (buttons, etc)
-
-It is a good idea to make buttons indicate a loading state when awaiting an API call. All `<uui-button>` support the `.state` property, which you can set around API calls:
-
-```typescript
-@state()
-private _buttonState: UUIButtonState = undefined;
-
-private _getStatus() {
-  this._buttonState = 'waiting';
-
-  [...await...]
-
-  this._buttonState = 'success';
-}
-```
-
-## Making the dashboard visible
-
-### Add to internal manifests
-
-All items are declared in a `manifests.ts` file, which is located in each section directory.
-
-To declare the Published Cache Status Dashboard as a new manifest, we need to add the section as a new json object that would look like this:
-
-```typescript
-{
-	type: 'dashboard',
-	alias: 'Umb.Dashboard.PublishedStatus',
-	name: 'Published Status Dashboard',
-	elementName: 'umb-dashboard-published-status',
-	element: () => import('./published-status/dashboard-published-status.element.js'),
-	weight: 200,
-	meta: {
-		label: 'Published Status',
-		pathname: 'published-status',
-	},
-	conditions: [
-		{
-			alias: UMB_SECTION_ALIAS_CONDITION_ALIAS,
-			match: 'Umb.Section.Settings',
-		},
-	],
-},
-```
-
-Let’s go through each of these properties…
-
--   Type: can be one of the following:
-
-    -   section - examples include: `Content`, `Media`
-    -   dashboard - a view within a section. Examples include: the welcome dashboard
-    -   propertyEditorUi
-    -   editorView
-    -   propertyAction
-    -   tree
-    -   editor
-    -   treeItemAction
-
--   Alias: is the unique key used to identify this item.
--   Name: is the human-readable name for this item.
-
--   ElementName: this is the customElementName declared on the element at the top of the file i.e
-
-```typescript
-@customElement('umb-dashboard-published-status')
-```
-
--   Js: references a function call to import the file that the element is declared within
-
--   Weight: allows us to specify the order in which the dashboard will be displayed within the tabs bar
-
--   Meta: allows us to reference additional data - in our case, we can specify the label that is shown in the tabs bar and the pathname that will be displayed in the URL
-
--   Conditions: allows us to specify the conditions that must be met for the dashboard to be displayed. In our case, we are specifying that the dashboard will only be displayed within the Settings section
-
-## API mock handlers
-
-Running the app with `npm run dev`, you will quickly notice the API requests turn into 404 errors. To hit the API, we need to add a mock handler to define the endpoints that our dashboard will call. In the case of the Published Cache Status section, we have several calls to work through. Let’s start by looking at the call to retrieve the current status of the cache:
-
-![Published Status Dashboard](/.github/img/contributing/status-of-cache.png)
-
-From the existing functionality, we can see that this is a string message that is received as part of a `GET` request from the server.
-
-So to define this, we must first add a handler for the Published Status called `published-status.handlers.ts` within the mocks/domains folder. In this file we will have code that looks like the following:
-
-```typescript
-const { rest } = window.MockServiceWorker;
-import { umbracoPath } from "@umbraco-cms/backoffice/utils";
-
-export const handlers = [
-    rest.get(umbracoPath("/published-cache/status"), (_req, res, ctx) => {
-        return res(
-            // Respond with a 200 status code
-            ctx.status(200),
-            ctx.json<string>(
-                "Database cache is ok. ContentStore contains 1 item and has 1 generation and 0 snapshot. MediaStore contains 5 items and has 1 generation and 0 snapshot."
-            )
-        );
-    }),
-];
-```
-
-This is defining the `GET` path that we will call through the resource: `/published-cache/status`
-
-It returns a `200 OK` response and a string value with the current “status” of the published cache for us to use within the element
-
-An example `POST` is similar. Let’s take the “Refresh status” button as an example:
-
-![Published Status Dashboard](/.github/img/contributing/refresh-status.png)
-
-From our existing functionality, we can see that this makes a `POST` call to the server to prompt a reload of the published cache. So we would add a new endpoint to the mock handler that would look like:
-
-```typescript
-rest.post(umbracoPath('/published-cache/reload'), async (_req, res, ctx) => {
- return res(
-    // Simulate a 1 second delay for the benefit of the UI
-    ctx.delay(1000)
-    // Respond with a 201 status code
-    ctx.status(201)
- );
-})
-```
-
-Which is defining a new `POST` endpoint that we can add to the core API fetcher using the path `/published-cache/reload`.
-
-This call returns a simple `OK` status code and no other object.
-
-## Storybook stories
-
-We try to make good Storybook stories for new components, which is a nice way to work with a component in an isolated state. Imagine you are working with a dialog on page 3 and have to navigate back to that every time you make a change - this is now eliminated with Storybook as you can just make a story that displays that step. Storybook can only show one component at a time, so it also helps us to isolate view logic into more and smaller components, which in turn are more testable.

-
-## Testing
-
-There are two testing tools on the backoffice: unit testing and end-to-end testing.
-
-### Unit testing
-
-We are using a tool called Web Test Runner which spins up a bunch of browsers using Playwright with the well-known jasmine/chai syntax. It is expected that any new component/element has a test file named “&lt;component>.test.ts”. It will automatically be picked up and there are a set of standard tests we apply to all components, which checks that they are registered correctly and they pass accessibility testing through Axe.
-
-Working with playwright: [https://playwright.dev/docs/intro](https://playwright.dev/docs/intro)
-
-## Putting it all together
-
-When we are finished with the dashboard we will hopefully have something akin to this [real-world example of the actual dashboard that was migrated](https://github.com/umbraco/Umbraco.CMS.Backoffice/tree/main/src/backoffice/settings/dashboards/published-status).

-# **Contributing to Localization in the Backoffice**
-
-Do you want to help keep our translations accurate and up to standard? 🌍✨
-
-Your input makes a real difference! By reviewing, refining, or suggesting improvements, you ensure that our translations remain clear, consistent, and user-friendly for everyone.
-
-
-## **How Can I Contribute?**
-
-To contribute to localization in the Backoffice, follow this step-by-step guide:
-
-
-### **1. Change the Language in Backoffice**
-
-
-
-1. Open the Backoffice, click on your profile icon in the top-right corner, and select "Edit." 
-
-
-
-![Menubar profile image](/.github/img/contributing/ProfileImage.png "Menubar profile image")
-
-
-
-![Edit button inside profile](/.github/img/contributing/editBtn.png "Edit button inside profile")
-
-
-2. Under "UI Culture," select the language you want to review from the dropdown menu. 
-
-
-
-![Dropdown of languages in Umbraco](/.github/img/contributing/uiCulture.png "Dropdown of languages in Umbraco")
-
-
-
-### **2. Find a Translation Error**
-
-
-
-1. Navigate through the Backoffice and check if everything is translated correctly. 
-
-2. When you find a translation error, right-click on it and select "Inspect." 
-
-3. Look for the nearest element that starts with `umb-` and has a name indicating something specific to the given location. 
- 
-    **Example:**  
-
-    * The closest parent element should be specific, such as `umb-document-type-workspace-view-settings` instead of a generic element like `umb-property-layout.`
-
-
-### **3. Find the Code in VS Code**
-
-
-
-1. Open VS Code and search for the nearest `umb-` element you identified. 
-
-
-
-![Search for nearest umb element in code](/.github/img/contributing/searchInVsCode.png "Search for nearest umb element in code")
-
-2. Scroll down to find `render() {` and look for the element label that needs updating. 
-
-
-![Find render and label in code](/.github/img/contributing/renderCode.png "Find render and label in code")
-
-3. If the label is hardcoded, it must be updated. 
- 
-    **Example:**  
-    `label="Vary by culture"`
-
-
-### **4. Find the Correct Translation**
-
-
-
-1. Open the `en.ts` or `en-us.ts` file and search for relevant keywords. \
- \
-    **Example:** 
-
-    * If the text is "Vary by culture," search for `vary`, `culture`, or `Vary by culture`. 
-
-
-2. Once you find the translation, take the element name and search for it in the target language file (e.g., `da-dk.ts` for Danish). 
-
-
-![Search for translation in language files](/.github/img/contributing/searchingThroughLanguageFiles.png "Search for translation in language files")
-
-3. If a translation exists, insert it into the label element found earlier. 
-
-
-
-### **5. Insert the Translation**
-
-To display the new translation correctly, insert the following code inside the label element:
-
-`${this.localize.term('action_key')}`
-
-Replace `action_key` with the correct translation key.
-
-**Example:**
-
-`${this.localize.term('contentTypeEditor_allowVaryByCulture')}`
-
-![Localization code snippet](/.github/img/contributing/localizationCodeSnippetInCode.png "Localization code snippet")
-
-
-Save the changes and return to the Backoffice to see the update.
-
-
-![Changes in backoffice after changes in code](/.github/img/contributing/changedBackofficeAfterLocalization.png "Changes in backoffice after changes in code")
-
-
-
-### **6. Commit and Push**
-
-
-
-1. Commit your changes to a new temporary branch (avoid committing directly to `main`). 
-
-2. Push the changes to your fork on GitHub.
-
-
-### **7. Create a Pull Request**
-
-
-
-1. In your forked repository on GitHub (`https://github.com/[YourUsername]/Umbraco-CMS`), a banner will appear stating that you pushed a new branch. 
-
-2. Click the button to create a pull request and follow the instructions.

-If you can’t find the translation you need, it may not exist yet. In this case, you can create a new action with related keys.
-
-
-### **1. Ensure It Doesn’t Already Exist**
-
-Search thoroughly in `en.ts` or `en-us.ts` for all relevant keywords.
-
-
-### **2. Create an Action**
-
-
-
-1. Choose a meaningful name for the action to avoid confusion. \
- \
- **Example:** Translation for the Data Type "Color Picker." 
-
-    * **Good name:** `colorPickerConfigurations`
-    * **Bad name:** `colorpicker`
-2. A specific action name prevents unnecessarily long key names. 
-
-3. Define the action: 
-
-
-
-### **3. Create Keys**
-
-
-
-1. Use clear and descriptive key names. \
- \
- **Example:**
-    * **Good name:** `colorsTitle`
-    * **Bad name:** `colors`
-2. Add the necessary keys inside the action with proper translations.

-
-
-
-## **I Can’t Find a <code>render()</code> Code in VS Code**
-
-In some cases, such as Data Types, the label might not be inside `render()`. Instead, it may be in a manifest file.
-
-
-### 1. Search for the Text
-
-Copy the text from the Backoffice and search for it in the code.
-
-
-### 2. Open the Manifest File
-
-Once you find the relevant manifest file, open it to confirm you’re in the right place.
-
-
-### 3. Change the Label
-
-In Markdown files, localization is slightly different. Instead of:
-`${this.localize.term('action_key')}`
-
-Use: `#action_key`
-
-**Example:**
-`#colorPickerConfigurations_showLabelTitle`
-
-### 4. Change the Description
-
-For descriptions in Markdown files, use:
-`{umbLocalize: action_key}`
-
-**Example:**
-`{umbLocalize: colorPickerConfigurations_showLabelDescription}`
-
-
-### 5. Save and Verify
-
-Once all changes are made, your manifest should look something like this:
-
-
-![Localization changes to manifest files](/.github/img/contributing/finishedManifestAfterLocalizatonChanges.png "Localization changes to manifest files")

-## Working Effectively
-
-Bootstrap, build, and test the repository:
-
--   Install .NET SDK (version specified in global.json):
-    -   `curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --version $(jq -r '.sdk.version' global.json)`
-    -   `export PATH="/home/runner/.dotnet:$PATH"`
--   Install Node.js (version specified in src/Umbraco.Web.UI.Client/.nvmrc):
-    -   `curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.0/install.sh | bash`
-    -   `export NVM_DIR="$HOME/.nvm" && [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"`
-    -   `nvm install $(cat src/Umbraco.Web.UI.Client/.nvmrc) && nvm use $(cat src/Umbraco.Web.UI.Client/.nvmrc)`
--   Fix shallow clone issue (required for GitVersioning):
-    -   `git fetch --unshallow`
--   Restore packages:
-    -   `dotnet restore` -- takes 50 seconds. NEVER CANCEL. Set timeout to 90+ seconds.
--   Build the solution:
-    -   `dotnet build` -- takes 4.5 minutes. NEVER CANCEL. Set timeout to 10+ minutes.
--   Install and build frontend:
-    -   `cd src/Umbraco.Web.UI.Client`
-    -   `npm ci --no-fund --no-audit --prefer-offline` -- takes 11 seconds.
-    -   `npm run build:for:cms` -- takes 1.25 minutes. NEVER CANCEL. Set timeout to 5+ minutes.
--   Install and build Login
-    -   `cd src/Umbraco.Web.UI.Login`
-    -   `npm ci --no-fund --no-audit --prefer-offline`
-    -   `npm run build`
--   Run the application:
-    -   `cd src/Umbraco.Web.UI`
-    -   `dotnet run --no-build` -- Application runs on https://localhost:44339 and http://localhost:11000
-
-Check out [BUILD.md](./BUILD.md) for more detailed instructions.
-
-## Validation
-
--   ALWAYS run through at least one complete end-to-end scenario after making changes.
--   Build and unit tests must pass before committing changes.
--   Frontend build produces output in src/Umbraco.Web.UI.Client/dist-cms/ which gets copied to src/Umbraco.Web.UI/wwwroot/umbraco/backoffice/
--   Always run `dotnet build` and `npm run build:for:cms` before running the application to see your changes.
--   For login-only changes, you can run `npm run build` from src/Umbraco.Web.UI.Login and then `dotnet run --no-build` from src/Umbraco.Web.UI.
--   For frontend-only changes, you can run `npm run dev:server` from src/Umbraco.Web.UI.Client for hot reloading.
--   Frontend changes should be linted using `npm run lint:fix` which uses Eslint.
-

-## Common Tasks
-
-### Running Umbraco in Different Modes
-
-**Production Mode (Standard Development)**
-Use this for backend development, testing full builds, or when you don't need hot reloading:
-
-1. Build frontend assets: `cd src/Umbraco.Web.UI.Client && npm run build:for:cms`
-2. Run backend: `cd src/Umbraco.Web.UI && dotnet run --no-build`
-3. Access backoffice: `https://localhost:44339/umbraco`
-4. Application uses compiled frontend from `wwwroot/umbraco/backoffice/`
-
-**Vite Dev Server Mode (Frontend Development with Hot Reload)**
-Use this for frontend-only development with hot module reloading:
-
-1. Configure backend for frontend development - Add to `src/Umbraco.Web.UI/appsettings.json` under `Umbraco:CMS:Security`:
-    ```json
-    "BackOfficeHost": "http://localhost:5173",
-    "AuthorizeCallbackPathName": "/oauth_complete",
-    "AuthorizeCallbackLogoutPathName": "/logout",
-    "AuthorizeCallbackErrorPathName": "/error",
-    "BackOfficeTokenCookie": {
-      "SameSite": "None"
-    }
-    ```
-2. Run backend: `cd src/Umbraco.Web.UI && dotnet run --no-build`
-3. Run frontend dev server: `cd src/Umbraco.Web.UI.Client && npm run dev:server`
-4. Access backoffice: `http://localhost:5173/` (no `/umbraco` prefix)
-5. Changes to TypeScript/Lit files hot reload automatically
-
-**Important:** Remove the `BackOfficeHost` configuration before committing or switching back to production mode.
-
-### Backend-Only Development
-
-For backend-only changes, disable frontend builds:
-
--   Comment out the target named "BuildStaticAssetsPreconditions" in src/Umbraco.Cms.StaticAssets.csproj:
-    ```
-    <!--<Target Name="BuildStaticAssetsPreconditions" BeforeTargets="AssignTargetPaths">
-      [...]
-    </Target>-->
-    ```
--   Remember to uncomment before committing
-
-### Building NuGet Packages
-
-To build custom NuGet packages for testing:
-
-```bash
-dotnet pack -c Release -o Build.Out
-dotnet nuget add source [Path to Build.Out folder] -n MyLocalFeed
-```
-
-### Regenerating Frontend API Types
-
-When changing Management API:
-
-```bash
-cd src/Umbraco.Web.UI.Client
-npm run generate:server-api-dev
-```
-
-Also update OpenApi.json from /umbraco/swagger/management/swagger.json
-
-## Database Setup
-
-Default configuration supports SQLite for development. For production-like testing:
-
--   Use SQL Server/LocalDb for better performance
--   Configure connection string in src/Umbraco.Web.UI/appsettings.json
-
-## Clean Up / Reset
-
-To reset development environment:
-
-```bash
-# Remove configuration and database
-rm src/Umbraco.Web.UI/appsettings.json
-rm -rf src/Umbraco.Web.UI/umbraco/Data
-
-# Full clean (removes all untracked files)
-git clean -xdf .
-```
-
-## Version Information
-
--   Target Framework: .NET (version specified in global.json)
--   Current Version: (specified in version.json)
--   Node.js Requirement: (specified in src/Umbraco.Web.UI.Client/.nvmrc)
--   npm Requirement: Latest compatible version
-
-## Known Issues
-
--   Build requires full git history (not shallow clone) due to GitVersioning
--   Some NuGet package security warnings are expected (SixLabors.ImageSharp vulnerabilities)
--   Frontend tests require Playwright browser installation: `npx playwright install`
--   Older Node.js versions may show engine compatibility warnings (check .nvmrc for current requirement)
-
-## Timing Expectations
-
-**NEVER CANCEL** these operations - they are expected to take time:
-
-| Operation               | Expected Time | Timeout Setting |
-| ----------------------- | ------------- | --------------- |
-| `dotnet restore`        | 50 seconds    | 90+ seconds     |
-| `dotnet build`          | 4.5 minutes   | 10+ minutes     |
-| `npm ci`                | 11 seconds    | 30+ seconds     |
-| `npm run build:for:cms` | 1.25 minutes  | 5+ minutes      |
-| `npm test`              | 2 minutes     | 5+ minutes      |
-| `npm run lint`          | 1 minute      | 5+ minutes      |
-| Unit tests              | 1 minute      | 5+ minutes      |
-| Integration tests       | Variable      | 10+ minutes     |
-
-Always wait for commands to complete rather than canceling and retrying.

-
-### Architecture Layers
-
-**Dependency Flow** (unidirectional, always flows inward):
-
-```
-Web.UI → Web.Common → Infrastructure → Core
-                ↓
-          Api.Management → Api.Common → Infrastructure → Core
-                ↓
-          Api.Delivery → Api.Common → Infrastructure → Core
-```
-
-**Key Principle**: Core has NO dependencies (pure contracts). Infrastructure implements Core. Web/APIs depend on Infrastructure.
-
-### Project Dependencies
-
-**Core Layer**:
-- `Umbraco.Core` → No dependencies (only Microsoft.Extensions.*)
-
-**Infrastructure Layer**:
-- `Umbraco.Infrastructure` → `Umbraco.Core`
-- `Umbraco.PublishedCache.*` → `Umbraco.Infrastructure`
-- `Umbraco.Examine.Lucene` → `Umbraco.Infrastructure`
-- `Umbraco.Cms.Persistence.*` → `Umbraco.Infrastructure`
-
-**Web Layer**:
-- `Umbraco.Web.Common` → `Umbraco.Infrastructure` + caching + search
-- `Umbraco.Web.UI` → `Umbraco.Web.Common` + all features
-
-**API Layer**:
-- `Umbraco.Cms.Api.Common` → `Umbraco.Web.Common`
-- `Umbraco.Cms.Api.Management` → `Umbraco.Cms.Api.Common`
-- `Umbraco.Cms.Api.Delivery` → `Umbraco.Cms.Api.Common`

-## 3. Teamwork & Collaboration
-
-### Branching Strategy
-
-- **Main branch**: `main` (protected)
-- **Branch naming convention**: `v<version>/<type>/<description>`
-
-**Format**: `v{major-version}/{type}/{kebab-case-description}`
-
-**Version**: Read from `version.json` in the repository root. Use the major version number (e.g., `v17` for version 17.x.x).
-
-**Types**:
-| Type | Use Case |
-|------|----------|
-| `feature` | New feature being introduced to the product |
-| `bugfix` | Fix to an existing issue with the product |
-| `qa` | Adding or updating unit, integration, or end-to-end tests |
-| `improvement` | Update to something that already exists but isn't broken (UI finessing, refactoring) |
-| `task` | Update that doesn't directly impact product behavior (dependency updates, build pipeline) |
-
-**Description**: A short, kebab-case description (a few words). This should be prefixed with the GitHub issue number if the update is related to resolving a tracked issue.
-
-**Examples**:
-```
-v17/bugfix/12345-correct-display-of-pending-migrations
-v17/feature/add-webhook-support
-v17/improvement/optimize-content-cache
-v17/qa/add-media-service-tests
-v17/task/update-ef-core-dependency
-```
-
-See `.github/CONTRIBUTING.md` for full guidelines.
-
-### Pull Request Process
-
-- **PR Template**: `.github/pull_request_template.md`
-- **Required CI Checks**:
-  - All tests pass
-  - Code formatting (dotnet format)
-  - No build warnings
-- **Merge Strategy**: Squash and merge (via GitHub UI)
-- **Reviews**: Required from code owners
-
-#### PR Naming Convention
-
-Use the format: `Area: Description (closes #IssueID)`
-
-**Examples**:
-| Area | Description | Issue |
-|------|-------------|-------|
-| Relations: | Move persistence of relations from repository into notification handlers | (closes #00000) |
-| Management API: | Correct the population of the parent for sibling items when retrieved under a folder | |
-| Docs: | Updated contributing guidelines to welcome contributions on bugfixes | |
-
-**Area**: The feature or aspect affected (e.g., UFM, TipTap, Docs, Segmentation, Migrations). Helps readers quickly understand what is being changed.
-
-**Description Best Practices**:
-- Include the area of change (Relations, Management API, etc.)
-- Describe the change and its impact
-- Be specific, not vague (describe "a golden retriever" not just "a dog")
-
-**Issue Linking**: Add `(closes #IssueID)` to auto-close linked issues on merge.
-
-### Commit Messages
-
-Follow Conventional Commits format:
-```
-<type>(<scope>): <description>
-
-Types: feat, fix, docs, style, refactor, test, chore
-Scope: project name (core, web, api, etc.)
-
-Examples:
-feat(core): add IContentService.GetByIds method
-fix(api): resolve null reference in schema handler
-docs(web): update routing documentation
-```
-
-### Code Owners
-
-Project ownership is distributed across teams. Check individual project directories for ownership.
-
----
-
-## 4. Architecture Patterns
-
-### Core Architectural Decisions
-
-1. **Layered Architecture with Dependency Inversion**
-   - Core defines contracts (interfaces)
-   - Infrastructure implements contracts
-   - Web/APIs consume implementations via DI
-
-2. **Interface-First Design**
-   - All services defined as interfaces in Core
-   - Enables testing, polymorphism, extensibility
-
-3. **Notification Pattern** (not C# events)
-   - See `/src/Umbraco.Core/CLAUDE.md` → "2. Notification System (Event Handling)"
-
-4. **Composer Pattern** (DI registration)
-   - See `/src/Umbraco.Core/CLAUDE.md` → "3. Composer Pattern (DI Registration)"
-
-5. **Scoping Pattern** (Unit of Work)
-   - See `/src/Umbraco.Core/CLAUDE.md` → "5. Scoping Pattern (Unit of Work)"
-
-6. **Attempt Pattern** (operation results)
-   - `Attempt<TResult, TStatus>` instead of exceptions
-   - Strongly-typed operation status enums
-
-### Key Design Patterns Used
-
-- **Repository Pattern** - Data access abstraction
-- **Unit of Work** - Scoping for transactions
-- **Builder Pattern** - `ProblemDetailsBuilder` for API errors
-- **Strategy Pattern** - OpenAPI handlers (schema ID, operation ID)
-- **Options Pattern** - All configuration via `IOptions<T>`
-- **Factory Pattern** - Content type factories
-- **Mediator Pattern** - Notification aggregator
-
----
-
-## 5. Project-Specific Notes
-
-### Centralized Package Management
-
-**All NuGet package versions** are centralized in `Directory.Packages.props`. Individual projects do NOT specify versions.
-
-```xml
-<!-- Individual projects reference WITHOUT version -->
-<PackageReference Include="Swashbuckle.AspNetCore" />
-
-<!-- Versions defined in Directory.Packages.props -->
-<PackageVersion Include="Swashbuckle.AspNetCore" Version="6.5.0" />
-```
-
-### Build Configuration
-
-- `Directory.Build.props` - Shared properties (target framework, company, copyright)
-- `.editorconfig` - Code style rules
-- `.globalconfig` - Roslyn analyzer rules
-
-### Persistence Layer - NPoco and EF Core
-
-The repository contains BOTH (actively supported):
-- **Current**: NPoco-based persistence (`Umbraco.Cms.Persistence.Sqlite`, `Umbraco.Cms.Persistence.SqlServer`) - widely used and fully supported
-- **Future**: EF Core-based persistence (`Umbraco.Cms.Persistence.EFCore.*`) - migration in progress
-
-**Note**: The codebase is actively migrating to EF Core, but NPoco remains the primary persistence layer and is not deprecated. Both are fully supported.
-
-### Authentication: OpenIddict
-
-All APIs use **OpenIddict** (OAuth 2.0/OpenID Connect):
-- Reference tokens (not JWT) for better security
-- **Secure cookie-based token storage** (v17+) - tokens stored in HTTP-only cookies with `__Host-` prefix
-- Tokens are redacted from client-side responses and passed via secure cookies only
-- ASP.NET Core Data Protection for token encryption
-- Configured in `Umbraco.Cms.Api.Common`
-- API requests must include credentials (`credentials: include` for fetch)
-
-**Load Balancing Requirement**: All servers must share the same Data Protection key ring.
-
-### Content Caching Strategy
-
-**HybridCache** (`Umbraco.PublishedCache.HybridCache`):
-- In-memory cache + distributed cache support
-- Published content only (not draft)
-- Invalidated via notifications and cache refreshers
-
-### API Versioning
-
-APIs use `Asp.Versioning.Mvc`:
-- Management API: `/umbraco/management/api/v{version}/*`
-- Delivery API: `/umbraco/delivery/api/v{version}/*`
-- OpenAPI/Swagger docs per version
-
-### Known Limitations
-
-1. **Circular Dependencies**: Avoided via `Lazy<T>` or event notifications
-2. **Multi-Server**: Requires shared Data Protection key ring and synchronized clocks (NTP)
-3. **Database Support**: SQL Server, SQLite

-
-### Design Patterns
-
-1. **Strategy Pattern** - `ISchemaIdHandler`, `IOperationIdHandler` (extensible via inheritance)
-2. **Builder Pattern** - `ProblemDetailsBuilder` for fluent error responses
-3. **Options Pattern** - All configuration via `IConfigureOptions<T>`
-
----
-
-## 2. Commands
-
-See "Quick Reference" section at bottom for common commands.
-
----
-
-## 3. Key Patterns
-
-### Virtual Handlers for Extensibility
-
-Handlers are intentionally virtual to allow consuming APIs to override:
-
-```csharp
-// NOTE: Left unsealed on purpose, so it is extendable.
-public class SchemaIdHandler : ISchemaIdHandler
-{
-    public virtual bool CanHandle(Type type) { }
-    public virtual string Handle(Type type) { }
-}
-```
-
-**Why**: Management and Delivery APIs can customize schema/operation ID generation.
-
-### Schema ID Sanitization (OpenApi/SchemaIdHandler.cs:24-29, 32)
-
-```csharp
-// Add "Model" suffix to avoid TypeScript name clashes (lines 24-29)
-if (name.EndsWith("Model") == false)
-{
-    // because some models names clash with common classes in TypeScript (i.e. Document),
-    // we need to add a "Model" postfix to all models
-    name = $"{name}Model";
-}
-
-// Remove invalid characters to prevent OpenAPI generation errors (line 32)
-return Regex.Replace(name, @"[^\w]", string.Empty);
-```
-
-### Polymorphic Deserialization (Serialization/UmbracoJsonTypeInfoResolver.cs:29-35)
-
-```csharp
-// IMPORTANT: do NOT return an empty enumerable here. it will cause nullability to fail on reference
-// properties, because "$ref" does not mix and match well with "nullable" in OpenAPI.
-if (type.IsInterface is false)
-{
-    return new[] { type };
-}
-```
-
-**Why**: Interfaces must return concrete types to avoid OpenAPI schema conflicts.
-
----
-
-## 4. Testing
-
-**Location**: No direct tests - tested via integration tests in consuming APIs
-
-**How to test changes**:
-```bash
-# Run integration tests that exercise this library
-dotnet test tests/Umbraco.Tests.Integration/
-
-# Verify OpenAPI generation
-# 1. Run Management API
-# 2. Navigate to /umbraco/swagger/
-# 3. Check schema IDs and operation IDs
-```
-
-**Focus areas when testing**:
-- OpenAPI document generation (schema IDs, operation IDs)
-- Polymorphic JSON serialization/deserialization
-- OpenIddict authentication flow
-- Problem details formatting
-
----
-
-## 5. OpenIddict Authentication
-
-### Key Configuration (DependencyInjection/UmbracoBuilderAuthExtensions.cs)
-
-**Reference Tokens over JWT** (line 76-80):
-```csharp
-// Enable reference tokens
-// - see https://documentation.openiddict.com/configuration/token-storage.html
-options
-    .UseReferenceAccessTokens()
-    .UseReferenceRefreshTokens();
-```
-
-**Why**: More secure (revocable), better for load balancing, uses ASP.NET Core Data Protection.
-
-**Token Lifetime** (line 88-91):
-```csharp
-// Make the access token lifetime 25% of the refresh token lifetime
-options.SetAccessTokenLifetime(new TimeSpan(timeOut.Ticks / 4));
-options.SetRefreshTokenLifetime(timeOut);
-```
-
-**PKCE Required** (line 59-63):
-```csharp
-// Enable authorization code flow with PKCE
-options
-    .AllowAuthorizationCodeFlow()
-    .RequireProofKeyForCodeExchange()
-    .AllowRefreshTokenFlow();
-```
-
-**Endpoints**: Backoffice `/umbraco/management/api/v1/security/*`, Member `/umbraco/member/api/v1/security/*`
-
-### Secure Cookie-Based Token Storage (v17+)
-
-**Implementation** (DependencyInjection/HideBackOfficeTokensHandler.cs):
-
-Back-office tokens are hidden from client-side JavaScript via HTTP-only cookies:
-
-```csharp
-private const string AccessTokenCookieKey = "__Host-umbAccessToken";
-private const string RefreshTokenCookieKey = "__Host-umbRefreshToken";
-
-// Tokens are encrypted via Data Protection and stored in cookies
-SetCookie(httpContext, AccessTokenCookieKey, context.Response.AccessToken);
-context.Response.AccessToken = "[redacted]";  // Client sees redacted value
-```
-
-**Key Security Features** (lines 143-165): `HttpOnly`, `IsEssential`, `Path="/"`, `Secure` (HTTPS), `__Host-` prefix
-
-**Configuration**: `BackOfficeTokenCookieSettings.Enabled` (default: true in v17+)
-
-**Implications**: Client-side cannot access tokens; encrypted with Data Protection; load balancing needs shared key ring; API requests need `credentials: include`
-
----
-
-## 6. Common Issues & Edge Cases
-
-### Polymorphic Deserialization Requires `$type`
-
-**Issue**: Deserializing to an interface without `$type` discriminator fails.
-
-**Handled in** (Json/NamedSystemTextJsonInputFormatter.cs:24-29):
-```csharp
-catch (NotSupportedException exception)
-{
-    // This happens when trying to deserialize to an interface, without sending the $type as part of the request
-    context.ModelState.TryAddModelException(string.Empty, new InputFormatterException(exception.Message, exception));
-    return await InputFormatterResult.FailureAsync();
-}
-```
-
-**Solution**: Clients must include `$type` property for interface types, or use concrete types.
-
-### Schema ID Collisions with TypeScript
-
-**Issue**: Type names like `Document` clash with TypeScript built-ins.
-
-**Solution**: Add "Model" suffix (OpenApi/SchemaIdHandler.cs:24-29)
-
-### Generic Type Handling
-
-**Issue**: `PagedViewModel<T>` needs flattened schema name.
-
-**Solution** (OpenApi/SchemaIdHandler.cs:41-50):
-```csharp
-private string HandleGenerics(string name, Type type)
-{
-    if (!type.IsGenericType)
-        return name;
-
-    // use attribute custom name or append the generic type names
-    // turns "PagedViewModel<RelationItemViewModel>" into "PagedRelationItem"
-    return $"{name}{string.Join(string.Empty, type.GenericTypeArguments.Select(SanitizedTypeName))}";
-}
-```
-
----
-
-## 7. Extending This Library
-
-### Adding a Custom OpenAPI Handler
-
-1. **Implement interface**:
-   ```csharp
-   public class MySchemaIdHandler : SchemaIdHandler
-   {
-       public override bool CanHandle(Type type)
-           => type.Namespace?.StartsWith("MyProject") is true;
-
-       public override string Handle(Type type)
-           => $"My{base.Handle(type)}";
-   }
-   ```
-
-2. **Register in consuming API**:
-   ```csharp
-   builder.Services.AddSingleton<ISchemaIdHandler, MySchemaIdHandler>();
-   ```
-
-**Note**: Handlers registered later take precedence in the selector.
-
-### Customizing Problem Details
-
-```csharp
-var problemDetails = new ProblemDetailsBuilder()
-    .WithTitle("Validation Failed")
-    .WithDetail("The request contains errors")
-    .WithType("ValidationError")
-    .WithOperationStatus(MyOperationStatus.ValidationFailed)
-    .WithRequestModelErrors(errors)
-    .Build();
-
-return BadRequest(problemDetails);
-```
-
----
-
-## 8. Project-Specific Notes
-
-### Why Virtual Handlers?
-
-**Decision**: Make `SchemaIdHandler`, `OperationIdHandler`, etc. virtual.
-
-**Why**: Management API and Delivery API have different schema ID requirements. Virtual methods allow override without rewriting the entire handler.
-
-**Example**: Management API might prefix all schemas with "Management", Delivery API with "Delivery".
-
-### Performance: Subtype Caching
-
-**Why**: Cache discovered subtypes (UmbracoJsonTypeInfoResolver.cs:14) to avoid expensive reflection calls
-
-### Known Limitations
-
-1. **Polymorphic Deserialization**:
-   - Requires `$type` discriminator in JSON for interfaces
-   - Only discovers types in Umbraco namespaces
-   - Not all .NET types are discoverable
-
-2. **OpenAPI Schema Generation**:
-   - Generic types are flattened (e.g., `PagedViewModel<T>` → `PagedTModel`)
-   - Type names may need "Model" suffix to avoid clashes
-
-3. **OpenIddict Multi-Server**:
-   - Requires shared Data Protection key ring
-   - All servers must have synchronized clocks (NTP)
-   - Reference tokens require database storage
-
-### External Dependencies
-
-**OpenIddict**:
-- OAuth 2.0 / OpenID Connect provider
-- Version: See `Directory.Packages.props`
-- Uses ASP.NET Core Data Protection for token encryption
-
-**Swashbuckle**:
-- OpenAPI 3.0 document generation
-- Custom filters: `EnumSchemaFilter`, `MimeTypeDocumentFilter`, `RemoveSecuritySchemesDocumentFilter`
-
-**Asp.Versioning**:
-- API versioning via `ApiVersion` attribute
-- API explorer integration for multi-version Swagger docs
-
-### Configuration
-
-**HTTPS**: `DisableTransportSecurityRequirement` for local dev only (ConfigureOpenIddict.cs:14). **Warning**: Never disable in production.
-
-### Usage Pattern
-
-Consuming APIs call `builder.AddUmbracoApiOpenApiUI().AddUmbracoOpenIddict()`
