Overview of this book

WinUI 3.0 takes a whole new approach to delivering Windows UI components and controls, and is able to deliver the same features on more than one version of Windows 10. Learn WinUI 3.0 is a comprehensive introduction to WinUI and Windows apps for anyone who is new to WinUI, Universal Windows Platform (UWP), and XAML applications. The book begins by helping you get to grips with the latest features in WinUI and shows you how XAML is used in UI development. You'll then set up a new Visual Studio environment and learn how to create a new UWP project. Next, you'll find out how to incorporate the Model-View-ViewModel (MVVM) pattern in a WinUI project and develop unit tests for ViewModel commands. Moving on, you'll cover the Windows Template Studio (WTS) new project wizard and WinUI libraries in a step-by-step way. As you advance, you'll discover how to leverage the Fluent Design system to create beautiful WinUI applications. You'll also explore the contents and capabilities of the Windows Community Toolkit and learn to create a new UWP user control. Toward the end, the book will teach you how to build, debug, unit test, deploy, and monitor apps in production. By the end of this book, you'll have learned how to build WinUI applications from scratch and modernize existing WPF and WinForms applications using WinUI controls.

Sharing the .NET 5 library with a WPF application

Class libraries are a great way to share code across multiple projects. It's also one way you can incrementally migrate applications to a new UI platform like WinUI. If you have your ViewModels or other business logic in separate .NET assemblies (or web services), the effort needed to build a new and modern UI is greatly reduced. If your existing desktop apps are single assembly monoliths, refactoring business logic into a separate class library is a great first step in a migration effort.

By defining our ViewModel in a separate .NET class library project, we can easily consume it in multiple UI projects. This separation also helps to ensure that the ViewModels will not have any dependencies on WinUI or other UI frameworks. Let's create a WPF project that also uses a WebView2 control:
