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
  • targeting older Windows versions before 10 1809
  • building web or mobile applications
