WinUI is Microsoft's modern UI framework providing Fluent Design controls and styles for building Windows applications, with WinUI 3 shipping as part of the Windows App SDK. It supports development in C# (.NET) or C++ targeting x86, x64, and ARM architectures.
Use cases
- build a modern Windows desktop app with Fluent Design
- create native Windows UI with XAML and C#
- migrate a UWP app to Windows App SDK
- build high-performance Windows apps in C++
- add modern controls and styles to a Win32 application
When to choose
- building Windows-only desktop applications with a modern native look
- you want Fluent Design controls backed by Microsoft support
- developing in C# or C++ for Windows 10 1809 or newer
When to avoid
- you need cross-platform UI (Windows, macOS, Linux) - consider Avalonia, Flutter, or .NET MAUI
