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.

Modernizing a WinForms application with XAML Islands

It's time to build a simple WinForms app that will host a custom UWP user control from another project. We will create a UWP project containing a simple input form and add it to a window in a .NET 5 WinForms project. You can use an earlier version of .NET Core if you like, but we will use .NET 5.0 in this example.

Creating a shared class library project

We will start off by creating the UWP class library. Class libraries help promote code reuse and encapsulate UI appearance and behavior. A NuGet repository is a great way to share code within your company and the OSS community. You can find out more information about NuGet hosting options on Microsoft Docs at https://docs.microsoft.com/en-us/nuget/hosting-packages/overview.

Note

We are creating a UWP class library because XAML Islands does not support WinUI 3.0 projects yet. Once this support is available, you will be able to follow this same technique with a WinUI...
