Overview of this book

WinUI 3 takes a whole new approach to delivering Windows UI components and controls and has the ability to deliver the same features across multiple versions of Windows. Learn WinUI 3 is a comprehensive introduction to WinUI and Windows apps for anyone who is new to WinUI and XAML applications. This updated second edition begins by helping you get to grips with the latest features in WinUI and shows you how XAML is used in UI development. The next set of chapters will help you set up a new Visual Studio environment, develop a new desktop project, incorporate the Model-View-ViewModel (MVVM) pattern in a WinUI project, and develop unit tests for ViewModel commands. Next, you’ll cover the basics of data access from WinUI projects with a step-by-step approach. As you advance, you’ll discover how to leverage the Fluent Design System to design beautiful WinUI applications. You’ll also explore the contents and capabilities of the Windows Community Toolkit and learn how to create cross-platform apps with markup and code from your project using Uno Platform. The concluding chapters will teach you how to build, debug, and deploy apps to the Microsoft Store. By the end of this book, you’ll have learned how to build WinUI applications from scratch and how to modernize existing desktop apps using WinUI 3 and the Windows App SDK.

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
