winui-dev-workflow skillA
winui-dev-workflow is agent-read markdown (skill) from microsoft/win-dev-skills: Build and run workflow for WinUI 3 apps with WinApp CLI 0.6+ — project creation with winapp new, project-mode winapp run, BuildAndRun.ps1 analyzer integration, crash diagnosis, and prerequisites. Use when creating, building, running, or fixing build errors in a WinUI 3 project..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

Do not install the template pack separately and do not create the output directory first. **Existing app** — read the `.csproj` to understand: - `<TargetFramework>` (e.g., `net10.0-windows10.0.26100.0`) - `<PackageReference>` versions (WindowsAppSDK, CommunityToolkit) - Project structure and established patterns ### Install Packages ```powershell dotnet add package <Name> ``` Never specify `--version` — omitting it gets the latest stable and avoids outdated API mismatches. ### Build & Run WinApp CLI 0.6+ builds a `.csproj` and launches it directly: ```powershell winapp run . --debug-output winapp run .\MyApp.csproj -c Release --arch arm64 ``` For normal development, prefer the included `BuildAndRun.ps1` wrapper. It invokes project-mode `winapp run`, injects the bundled `Microsoft.WindowsAppSDK.Analyzers`, and turns on `--debug-output` by default: ```powershell …
