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.

Creating a WinUI control library

A control library is a great way to reuse your WinUI controls across projects, much in the same way that .NET libraries enable projects to share business logic. This concept is not new to WinUI; you can create control libraries for most UI frameworks. We are going to create a control library with a user control containing two WinUI controls:

  • A TextBox to enter a URL where our users want that WebView2 to navigate
  • A reload Button to reload the current web page in WebView2

We will use one event to trigger the reload and another to notify the host that a new URL has been entered:

  1. Start by adding a new Control Library (WinUI in Desktop) project to the solution in your language of choice. Name the project WebViewBrowser.Controls.
  2. Remove Class1.cs from the project and use Add | New Item to add a new User Control (WinUI) named BrowserToolbar to the project.

    Note

    A User Control is best suited to our needs here. We want to define...
