winui-packaging skillA
winui-packaging is agent-read markdown (skill) from microsoft/win-dev-skills: MSIX packaging, code signing, and distribution for WinUI 3 apps — build for release, certificate generation (winapp cert generate), certificate trust, code signing (winapp sign), self-contained deployment, CI/CD with GitHub Actions, and Microsoft Store submission. Use when preparing for release, creating MSIX installers, managing certificates, setting up CI/CD packaging, or publishing to the Microsoft Store..
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.
What the file says
### Quick Reference | Task | Command | |------|---------| | Build for release | `.\BuildAndRun.ps1 . -c Release --arch x64 --no-launch` | | Package + sign | `winapp package <dir> --cert devcert.pfx` | | Generate + sign + package | `winapp package <dir> --generate-cert --install-cert` | | Generate dev certificate | `winapp cert generate` | | Trust certificate (admin) | `winapp cert install ./devcert.pfx` | | Sign existing file | `winapp sign ./app.msix ./devcert.pfx` | | Self-contained deployment | `winapp package <dir> --cert devcert.pfx --self-contained` | ### End-to-End Workflow #### Step 1: Build for Release Build the project in Release configuration without launching it. Use the `BuildAndRun.ps1` wrapper from the `winui-dev-workflow` skill — plain `dotnet build` does **not** load the bundled `Microsoft.WindowsAppSDK.Analyzers`, so release builds would ship without the analyzer gate that development builds get: ```powershell .\BuildAndRun.ps1 . -c Release --arch x64 --no-launch ``` …

How to install
mdr add microsoft/win-dev-skills/winui-packaging@git:20260826.26aa303mdr add microsoft/win-dev-skills/winui-packaging@sha256:b0651e31f098fc8bPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
