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.

We’ve made quite a bit of progress with the application in this chapter. While it’s not yet connected to a live data source, we have methods in place to add and remove items from the media collection in memory. In addition, the project has been refactored to use the MVVM pattern, moving all the existing view logic from the MainWindow code-behind file to a new MainViewModel class. The new MainViewModel class has no dependencies on the UI. Finally, we saw how integrating the MVVM Toolkit into the project can reduce the boilerplate code in our view models. These good software design habits will serve us well in the chapters ahead as we build more functionality onto the project.

In the next chapter, we will continue learning how to use the MVVM pattern to write robust, maintainable WinUI applications. We will cover some more advanced MVVM topics and learn some techniques for window management in a WinUI project.
