winui-dev-workflow

Create or Open a Project

New app — let WinApp CLI install/update the official templates and scaffold:

winapp new --name <AppName> --template winui-mvvm --template-version latest --use-defaults
cd <AppName>

Run winapp new --list to discover the currently installed template short names. 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
