Implementing auto-generated view models

Following the MVVM pattern often involves writing a lot of boilerplate code for properties with INotifyPropertyChanged support and commands. This task can be tedious and prone to errors caused by copy-pasting. Fortunately, there’s a solution to avoid writing this code manually: use the code generator available in CommunityToolkit.Mvvm.

Getting ready

Start with the project you got after executing the previous recipe (Decoupling the UI from the view model). This project is available at https://github.com/PacktPublishing/.NET-MAUI-Cookbook/tree/main/Chapter02/c2-DecoupleViewAndViewModel.

How to do it…

Let’s transform the view model from the previous recipe using the code generators from CommunityToolkit.Mvvm and see how much code we will save:
