Remarks

This exception typically indicates that the application's dependency resolver has not been initialized via UseReactiveUI, services.AddReactiveUI(), or custom DI registration. It can also surface when assemblies containing the default locator are trimmed out of the app package. Catch the exception at startup to log configuration issues and ensure the container registers an IViewLocator before resolving views.

Examples

 try
 {
 var view = ViewLocator.Current.ResolveView(viewModel);
 }
 catch (ViewLocatorNotFoundException ex)
 {
 logger.LogCritical(ex, "ReactiveUI was not initialized; cannot resolve views.");
