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.

Understanding the basics of DI

Before starting down the path of using DI in our project, we should take some time to understand what DI is and why it is fundamental for building modern applications. You will often see DI referenced with another related concept, Inversion of Control (IoC). Let’s discuss these two concepts by doing the following:

  • Clarify the relationship between them
  • Prepare you to use DI properly in this chapter

DI is used by modern developers to inject dependent objects into a class rather than creating instances of the objects inside the class. There are several ways to inject those objects:

  • Method injection: Objects are passed as parameters to a method in the class
  • Property injection: Objects are set through properties
  • Constructor injection: Objects are passed as constructor parameters

The most common method of DI is constructor injection. In this chapter, we will be using both property injection and constructor injection...
