Leveraging the MVVM Toolkit

We briefly introduced the MVVM Toolkit earlier in the chapter. In this section, we will update the MainViewModel to see how we can remove the need for a BindableBase class and reduce the amount of code in the view model itself:

1. Start by right-clicking on the solution file in Solution Explorer and select Manage NuGet Packages for Solution.
2. In the NuGet window, select the Browse tab and search for CommunityToolkit.Mvvm.
3. Select the CommunityToolkit.Mvvm package in the results and install the latest stable version (8.2.0 or later).
4. Close the NuGet window and open the MainViewModel class. The first thing we need to do to use the MVVM Toolkit’s source generators is update MainViewModel to be a partial class and have it inherit from CommunityToolkit.Mvvm.ComponentModel.ObservableObject instead of our own BindableBase class:

   public partial class MainViewModel : ObservableObject
