Overview of this book

WinUI 3.0 takes a whole new approach to delivering Windows UI components and controls, and is able to deliver the same features on more than one version of Windows 10. Learn WinUI 3.0 is a comprehensive introduction to WinUI and Windows apps for anyone who is new to WinUI, Universal Windows Platform (UWP), and XAML applications. The book begins by helping you get to grips with the latest features in WinUI and shows you how XAML is used in UI development. You'll then set up a new Visual Studio environment and learn how to create a new UWP project. Next, you'll find out how to incorporate the Model-View-ViewModel (MVVM) pattern in a WinUI project and develop unit tests for ViewModel commands. Moving on, you'll cover the Windows Template Studio (WTS) new project wizard and WinUI libraries in a step-by-step way. As you advance, you'll discover how to leverage the Fluent Design system to create beautiful WinUI applications. You'll also explore the contents and capabilities of the Windows Community Toolkit and learn to create a new UWP user control. Toward the end, the book will teach you how to build, debug, unit test, deploy, and monitor apps in production. By the end of this book, you'll have learned how to build WinUI applications from scratch and modernize existing WPF and WinForms applications using WinUI controls.

Gathering and analyzing App Center crash reports

The last topic we will cover in this chapter is monitoring application crashes with App Center. Because we added Crashes to the call to AppCenter.Start in App.xaml.cs, any crashes will automatically be reported to App Center's analytics. But how can we simulate a crash while we're developing an application?

To simulate a crash, add the following line of code to any application sometime after the AppCenter.Start call has been completed. Let's add it to the beginning of the SelectedMediaItem property setter in MainViewModel. Clicking on any media item in the collection will generate a crash for us. Use the #if DEBUG preprocessor directive to ensure that this will not happen in your application in production:

#if DEBUG
    Crashes.GenerateTestCrash();
#endif

Don't forget to add a using statement to the class as well:

using Microsoft.AppCenter.Crashes;
