Windows UI Library 2.7

WinUI 2.7 is the September 2021 release of the Windows UI Library (WinUI) for UWP applications (and desktop applications using XAML Islands).


For more information on building Windows desktop and UWP apps with the latest version of WinUI 3, see Windows UI Library 3.

The Windows UI Library (WinUI) is hosted on GitHub where we encourage you to file bug reports, feature requests and community code contributions.

All stable releases (and prereleases) are available for download from our GitHub release page or from our NuGet page.

WinUI packages can be added to Visual Studio projects through the NuGet package manager. For more information, see Getting started with the Windows UI 2 Library.

New or updated features for WinUI 2.7 include:


Badging is a non-intrusive and intuitive way to indicate notifications, display alerts, highlight new content, or draw focus to an area within an app. An InfoBadge is a small piece of UI that can be added into an app and customized to display a number, icon, or a simple dot.

Dot, icon, and numeric InfoBadges

InfoBadge is built into the NavigationView control. It can also be specified as a standalone element in the XAML tree, letting you place InfoBadge into any control or piece of UI that you choose.
