Development Flow

  • Uno Platform's WinUI/UWP XAML
    • Windows-first development
    • Faster compilation for most of the development cycle, including UI code. iOS, Android, WebAssembly, macOS and Linux can be tested for platform-specific features.
    • Ability to develop responsive layout in Windowed mode using Windows 10.
    • Allows for edit and continue support from VS2017+
    • Allows for UI and Non-UI code edit and continue support
  • Conditional platform features access
    • All XAML controls have access to native properties through conditional XAML
    • Ability to add native controls in XAML
  • Full WinUI/UWP availability at compile time
    • Allows for the compilation of open-source libraries that depend only on WinUI/UWP and multi-targeted nuget packages
      • XamlBehaviors library support
  • macOS Compilation
