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.

Why package your application? Well, an application package is the easiest way for WinUI applications and their dependencies to be installed in Windows. Today, when you run a WinUI project in Visual Studio, the integrated development environment (IDE) creates a package and deploys it locally. Packaging serves several other important purposes, outlined as follows:

  • Providing a clean uninstall: A packaging system ensures that any files installed or updated with an application are removed or restored to their previous state when the application is uninstalled
  • Bundling dependencies: The application package will bundle and deliver all your application’s dependencies, optimizing disk space by sharing files across installed...
