Chapter 13 Lets Get Graphical

Registering Your Widget

The last part in your implementation of the sketch widget is to register your view and view model with the MauiAppBuilder. Let’s open up the MauiProgram.cs file and add the following lines into the

CreateMauiApp method:

WidgetFactory.RegisterWidget<SketchWidgetView, SketchWidgetView Model>(SketchWidgetViewModel.DisplayName); builder.Services.AddTransient<SketchWidgetView>(); builder.Services.AddTransient<SketchWidgetViewModel>();
