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.

Advanced MVVM Concepts

After learning the basics of the MVVM pattern and its implementation in WinUI, it’s now time to build on that knowledge base to handle some more advanced techniques. Now, you will learn how to keep components loosely coupled and testable when adding new dependencies to the project.

Few modern applications have only a single page or window. There are MVVM techniques that can be leveraged to navigate between pages from a ViewModel command without being coupled to the UI layer.

In this chapter, you will learn about the following concepts:

  • Understanding the basics of Dependency Injection (DI)
  • Leveraging DI to expose ViewModel classes to WinUI views
  • Using MVVM and x:Bind to handle additional UI events with event handlers in the ViewModel
  • Navigating between pages with MVVM and DI

By the end of this chapter, you will have a deeper understanding of the MVVM pattern and will know how to decouple your view models from any external...
