Project Context

  • Location: ui/uno/Sundy.Uno/
  • Solution: Sundy.Uno.sln
  • Uno SDK: 6.5.0-dev.71
  • Targets: iOS, Android, WebAssembly, Desktop

Architecture

  • MVVM pattern with CommunityToolkit.Mvvm (same as Avalonia)
  • ViewModels shared across all platforms
  • Platform-specific code in Platforms/ subdirectories
  • XAML views (.xaml) with WinUI syntax

Key Patterns

// ViewModel pattern (identical to Avalonia)
public partial class MyViewModel : ObservableObject
{
    [ObservableProperty]
    private string _title;  // Generates Title property

    [RelayCommand]
    private void Save() { }  // Generates SaveCommand
}

Platform-Specific Code

// Use conditional compilation
#if __IOS__
    // iOS-specific code
#elif __ANDROID__
    // Android-specific code
#elif HAS_UNO_WASM
    // WebAssembly-specific code
#endif

File Locations

Coding Standards

  • Use file-scoped namespaces
  • Always use braces around control statements
  • Prefer primary constructors for DI
  • Write platform-agnostic XAML when possible
  • Use conditional compilation for platform-specific behavior
