WinUIHub is an opinionated, practical companion to the official WinUI 3 and Windows App SDK documentation. Where Microsoft Learn covers everything, WinUIHub focuses on what to use, what to avoid, and how to get it working today.

Note

WinUIHub is new. This section will grow into a guided path for developers starting a WinUI 3 app.

How the site is organised

• Recipes are short, focused solutions to one problem, like adding a tray icon or a custom title bar.
• Guides are longer explanations of concepts and trade-offs.
• Resources is a curated list of documentation, samples and libraries worth your time.
• Tools lists developer tools for building, packaging and debugging WinUI apps.
• Icons will let you search and copy Segoe Fluent Icons.
• AI Skills will provide WinUI knowledge packs for coding agents.

Version awareness

WinUI and the Windows App SDK change quickly. Every recipe states which Windows App SDK version it targets, whether it works in packaged and unpackaged apps, and when it was last verified.
