How can I find out whether you are using WinUI 2 or WinUI 3?

Question

Currently, I try to learn how to use UWP UI component, in WPF application.

I'm following the examples in https://github.com/rvinothrajendran/XamlIslands

However, may I know, how can I find out, whether the example is using WinUI 2, or WinUI 3?

Thanks.

If you look in the WPFXamlTemplate.csproj file, you'll see that it has a <PackageReference> to Microsoft.Toolkit.Wpf.UI.Controls 6.0.0-preview5.

This is known as the Windows Community Toolkit which is a separate project from Win UI.

It uses XAML Islands host the native UWP controls in the WPF application.
