Bootstrap, develop, and design modern WinUI 3 desktop applications with C# and the Windows App SDK using official Microsoft guidance, WinUI Gallery patterns,…
WinUI App Use this skill for WinUI 3 and Windows App SDK work that needs grounded setup guidance, app bootstrap, modern Windows UX decisions, or concrete implementation patterns. Required Flow Classify the task as environment/setup, new-app bootstrap, design, implementation, review, or troubleshooting. If the task is about preparing a machine for WinUI, auditing readiness, or creating a brand new app, start with the bundled setup-and-scaffold flow in this skill before broader design, implementation, or troubleshooting work: Pick the app name when the request is for a new app. Use the exact name the user gave when it is already a safe folder name. If the user did not give a name, derive a short PascalCase name from the request and state what you chose. Create the project in the user's current workspace unless they asked for another location. Do not use --force unless the user explicitly asked to overwrite existing files. Run the bundled WinGet configuration from the skill directory so the relative path stays exactly config.yaml: winget configure -f config.yaml --accept-configuration-agreements --disable-interactivity
