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.

Understanding MVVM

MVVM was introduced by Microsoft in 2005 and gained popularity with developers following the launch of Windows Presentation Foundation (WPF) and Silverlight because it lends itself so well to building applications with XAML. It is like the Presentation Model pattern, which was created by Martin Fowler – one of the most influential proponents of design patterns.

The MVVM pattern consists of the following three layers:

  • Model: The Model layer contains the application’s business logic and should perform all the data access operations. The View Model communicates with the Model to retrieve and save the application’s data.
  • View: The View layer is only responsible for the presentation of data in the application. The layout or structure is defined here, along with style definitions. This is the layer responsible for interacting with the user and receiving input events and data. The View is aware of the View Model only through data-binding...
