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.

Debugging WinUI Applications with Visual Studio

Good debugging skills are essential for developers. While .NET developers need to know how to use features including breakpoints and the Output and Immediate windows, WinUI project debugging adds another set of tools and techniques to master. There are issues that can arise in the UI layer with data binding, layout, and resources. You will learn how to use Live Visual Tree and Live Property Explorer and how to discover data binding errors with Visual Studio’s XAML Binding Failures window.

In this chapter, we will cover the following topics:

  • How to debug WinUI applications and work with breakpoints in ViewModels and service classes
  • How to debug data binding failures by leveraging the XAML Binding Failures window in Visual Studio and avoid common problems when binding to collections
  • Explore the Live Visual Tree window in Visual Studio to find layout problems in your XAML
  • Discover and use Live Property Explorer...
