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.

This will give us a cross-platform version of the application that we will run on Windows, Android, and WebAssembly in the sections ahead.

In order to keep things simple for our first project, we are going to migrate the code from the completed MyMediaCollection solution found in the completed code for Chapter 5, Exploring WinUI Controls. If you don’t have a copy of that code, you can get it from GitHub here: The easiest way to follow along with the instructions is to download the solution, but you can also create each class in the Uno Project solution and copy and paste the WinUI project code from the GitHub editor.

We are going to use the code from...
