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.

  • A Model class that defines an item in the collection
  • Some code to bind the collection of items to the UI
  • A XAML control to display the items

Building the model

We will start by building the model for the My Media Collection application. A model defines an entity and its attributes. Earlier in the chapter, we discussed some of the items' attributes we want to display in the UI. In order to display and (eventually) persist this information, we must create the model.

The initial version of our model will consist of two enums (ItemType and LocationType) in an Enums folder and two classes (Medium and MediaItem) in a Model folder, as illustrated in the following screenshot:
