Remarks

After registering View/ViewModel pairs via AddMvvmTransient<TView, TViewModel>(IServiceCollection) or AddMvvmSingleton<TView, TViewModel>(IServiceCollection), the system will:

• Register the ViewModel in DI
• Record the View ↔ ViewModel type mapping (TView is not registered in DI)
• Inject the DataContext via ViewModelLocator when AutoWireViewModel is set
• Instantiate the corresponding View via ViewLocator when EnableViewLocator is enabled on app options

Properties
