Uno Platform
Build cross-platform .NET applications with Uno Platform targeting WebAssembly, iOS, Android, macOS, Linux, and Windows from a single XAML/C# codebase.
Trigger On
- building cross-platform apps from a single C# and XAML codebase
- targeting WebAssembly, iOS, Android, macOS, Linux, and Windows simultaneously
- migrating WPF or UWP applications to cross-platform
- implementing pixel-perfect UI across all platforms
- using WinUI/UWP APIs on non-Windows platforms
Workflow
- Choose the right template — Uno Platform offers various templates for different scenarios
- Understand rendering modes — Skia vs native rendering affects performance and fidelity
- Apply MVVM or MVUX patterns — keep views dumb, logic in ViewModels
- Handle platform differences — use conditional XAML or partial classes
- Test on all target platforms — behavior varies across platforms
Deliver
- single codebase running on web, mobile, and desktop
- consistent UI/UX across all platforms
- platform-specific optimizations where needed
- MVVM or MVUX patterns for testability
Validate
- app builds and runs on all target platforms
- platform-specific features work correctly
- performance is acceptable on WebAssembly
- Hot Reload works during development
- no WPF/UWP-only APIs are used without fallbacks
