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.

Debugging in Visual Studio

There are several fundamental areas of debugging WinUI applications that we will be covering in this section. Some of these techniques are applicable to debugging other types of .NET applications, whereas others are specific to XAML and WinUI development. Throughout the book, we’ve run our projects with Visual Studio, which is an example of a local debugging session. We will explore other ways to debug local applications as well as remote applications.

Simple mistakes in XAML markup are not always apparent when we’re writing it, and this kind of problem is not detected by the compiler. In this section, we will see how to detect and avoid XAML markup issues and how to adhere to best practices.

Let’s get started by taking a closer look at debugging local applications.
