## What it does

This instruction file guides GitHub Copilot when working with the Power Apps component framework. It activates for `.ts`, `.tsx`, `.js`, `.json`, `.xml`, `.pcfproj`, and `.csproj` files. Copilot uses it to follow CLI workflows and packaging requirements for canvas applications.

Activating code components requires a Power Apps license alongside system administrator privileges. The setting resides in the Power Apps Admin Center under product features. Model-driven apps have this enabled out of the box, but canvas environments need manual activation.

Because controls running inside Power Apps Studio access security tokens, importing untrusted solutions introduces direct data exposure risks. Runtime updates also demand care. Simply deleting and re-adding a control will not update it; you must increment the `version` field in the manifest and reopen the app.

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/pcf-canvas-apps.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/pcf-canvas-apps.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/pcf-canvas-apps.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/pcf-canvas-apps.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/pcf-canvas-apps.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/pcf-canvas-apps.instructions.md

## When to use it
- handle Power Apps Studio security constraints for custom controls
- update manifest versioning so canvas apps load modified code
- configure component framework settings in the Power Platform Admin Center
- structure TypeScript and `.pcfproj` files for Microsoft Dataverse solutions

## Example prompts
- Help me configure properties in this PCF manifest for a canvas app
- Why isn't Power Apps Studio picking up my code changes after rebuilding?
- Review this component manifest against Power Apps Studio security rules

# Code Components for Canvas Apps

Professional developers can use Power Apps component framework to create code components that can be used in their canvas apps. App makers can use Power Apps component framework to create, import, and add code components to canvas apps using [Microsoft Power Platform CLI](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/get-powerapps-cli).

> **Note**: Certain APIs might not be available in canvas apps. We recommend that you check each API to determine where it's available.

## Security Considerations

> **Warning**: Code components contain code that may not be generated by Microsoft and can potentially access security tokens and data when rendered in Power Apps Studio. When adding code components to a canvas app, make sure that the code component solutions are from a trusted source. This vulnerability does not exist when playing the canvas app.

### Security Warning in Power Apps Studio

When you open a canvas app that contains code components in Power Apps Studio, a warning message about potentially unsafe code appears. Code components in the Power Apps Studio environment have access to security tokens; hence only components from trusted sources should be opened.

**Best Practices:**
- Administrators and system customizers should review and validate all code components before importing them into an environment
- Make components available to makers only after validation
- The `Default` publisher is shown when you import code components by using an unmanaged solution or when you have used `pac pcf push` to install your code component

## Prerequisites

- A Power Apps license is required. More information: [Power Apps component framework licensing](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/overview#licensing)
- System administrator privileges are required to enable the Power Apps component framework feature in the environment

## Enable the Power Apps Component Framework Feature

To add code components to an app, you need to enable the Power Apps component framework feature in each environment where you want to use them. By default, the Power Apps component feature is enabled for model-driven apps.

### Steps to Enable for Canvas Apps:

1. Sign in to [Power Apps](https://powerapps.microsoft.com/)
2. Select **Settings** ![Settings](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/media/settings.png), and then select **Admin Center**

   ![Settings and Admin Center](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/media/select-admin-center-from-settings.png)

3. On the left pane, select **Environments**, select the environment where you want to enable this feature, and then select **Settings**
4. Expand **Product**, and select **Features**
5. From the list of available features, turn on **Power Apps component framework for canvas apps**, and then select **Save**
