RJi.Mvvm.Wpf

A WPF MVVM framework built on CommunityToolkit.Mvvm and Microsoft.Extensions.DependencyInjection (.NET 8 / .NET Framework 4.8), designed for single-page navigation in small-to-medium projects.

⚠️ .NET Framework 4.8: Source generators require SDK-style project (Microsoft.NET.Sdk) with <LangVersion>latest</LangVersion>. See the full docs for migration steps.

The primary use case is industrial automation (工控) development. The navigation model is based on ContentControl zone switching — each zone displays one view at a time, supporting both full-page transitions and fixed-layout page switching. It does not adopt a multi-region caching architecture (where each region maintains its own independent view stack); instead, the navigation service manages a flat view stack with optional view caching per zone, keeping the mental model simple and predictable for scaffold-style projects.

  • MVVM Foundation — ObservableObject, RelayCommand, Messenger with automatic UI thread dispatch
  • Zero Reflection — Explicit View–ViewModel binding via generic methods at startup
  • Source Generators — CT.Mvvm ([ObservableProperty], [RelayCommand]) + framework ([NavigationTarget], [AddSingleton], [ViewModelLocator], etc.), single AddGeneratedRegistrations() call
  • Single-Page Navigation — UserControl inside ContentControl zones with lifecycle, history, and view caching
  • Dialog Windows — Built-in DialogWindow with lifecycle hooks, custom window support
  • DI Container — IServiceCollection-based, 12 DI attributes covering all lifetimes
  • Navigation Service — Zone registry, navigation confirmation (callback pattern), ViewModel locator
  • UI Thread Dispatching — IUIDispatcher interface for safe background-to-UI thread operations

2.2.0

Breaking changes:
• Removed IConfirmNavigationRequest.CanClose() — use ConfirmNavigationRequest only
• Removed Conductor/IChildLifecycle — replaced by Messenger/Navigation Parameters

New:
• DispatcherMessenger UIThread mode now uses InvokeAsync (aligned with Prism), no longer swallows exceptions
• ParameterCollection consolidated to Mvvm/Internal, removed duplicate from Dialogs

Fixes:
• ViewZoneRegistry.Contains no longer returns stale data for GC'd WeakReference entries
• DialogService no longer throws NullReferenceException when DataContext is null
• MessengerToken.GetHashCode non-zero to avoid dictionary hash collisions
• RJiApplication.ServiceProvider returns null after disposal instead of disposed container
• ViewZone internals use IDispatcherMessenger instead of IMessenger directly
