Overview of this book

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. The concluding chapters will teach you how to build, debug, and deploy apps to the Microsoft Store. By the end of this book, you’ll have learned how to build WinUI applications from scratch and how to modernize existing desktop apps using WinUI 3 and the Windows App SDK.

Use Mica in WinUI applications

Mica is another material that’s available to WinUI applications. You can think of Mica as an Acrylic background brush without the transparency. It creates the brush style based on the current desktop background color in Windows. There are two variants of the Mica material: Mica and Mica Alt. Mica Alt creates the same kind of opaque background as Mica, but it has stronger tinting.

Note

Mica is only available in Windows 11 and later. If your app uses Mica and is installed on Windows 10, it will not apply the material.

If you use the WinUI 3 Gallery and open the System Backdrops (Mica/Acrylic) page, you can launch a WinUI window and cycle through the Mica, Mica Alt, and Acrylic materials applied to the window background:

The code to set the system backdrop for a window is more involved than just applying a brush to the Fill property...
