Localized reading guide
winui-appPurpose, usage and source
Bootstrap, develop, and design modern WinUI 3 desktop applications with C# and the Windows App SDK using official Microsoft guidance, WinUI Gallery patterns, Windows App SDK samples, and CommunityToolkit components. Use when creating a brand new app, preparing a machine for WinUI, reviewing, refactoring, planning, troubleshooting, environment-checking, or setting up WinUI 3 XAML, controls, navigation, windowing, theming, accessibility, responsiveness, performance, deployment, or related Windows app design and development work.

What this Skill does
Bootstrap, develop, and design modern WinUI 3 desktop applications with C# and the Windows App SDK using official Microsoft guidance, WinUI Gallery patterns, Windows App SDK samples, and CommunityToolkit components. Use when creating a brand new app, preparing a machine for WinUI, reviewing, refactoring, planning, troubleshooting, environment-checking, or setting up WinUI 3 XAML, controls, navigation, windowing, theming, accessibility, responsiveness, performance, deployment, or related Windows app design and development work.
How the upstream workflow works
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.
Upstream passage · L6 ↗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:
Upstream passage · L10 ↗Reference Rules
Keep C# as the primary path. Mention C++ or C++/WinRT only when the difference is material. Preserve the conventions of an existing codebase instead of forcing a generic sample structure onto it.
Upstream passage · L87 ↗winget configure -f config.yaml --accept-configuration-agreements --disable-interactivityRequirements and setup
Environment Rules
Do not guess whether the machine is ready for WinUI development. Verify it. Use the bundled setup-and-scaffold flow in this skill for fresh setup, remediation, and first-project scaffolding instead of delegating to another skill.
Upstream passage · L75 ↗Limits and quality checks
No separate limits passage was selected from this file. This does not mean the Skill is safe for every input or environment. Review the complete source and validate your own result.
Start with a safe trial
- Check the supported host and the repository installation instructions. Keep the Skill directory and its referenced scripts, assets and documentation together; SKILL.md alone may omit dependencies.
- Give the agent your real input, desired output and acceptance criteria. Invocation syntax and available tools depend on the host; this site does not assume a universal install command.
- Try the source workflow in a disposable project or on a copy. Review operations that change files, remote services or billable resources before allowing them.
- Validate the output against the source quality checks and your own requirements. A successful trigger or a high repository Star count does not establish a correct result.
