If you want to migrate UWP to a Desktop app, you could migrate to Windows App SDK (Migrate from UWP to the Windows App SDK)
(XAML controls are about the same (namespace Microsoft instead of Windows), so it is easier)

There is no simple way how to achieve that.

XAML markup cannot be shared between UWP and WPF applications. They use different XAML parsers and different XAML "dialects".

You could create a new WPF application from scratch and basically rewrite all the views. If you develop your application according to the recommended MVVM pattern, you should be able to reuse most of your application logic/view model code. You can place a view model in a portable class library and reference it from WPF applications and UWP applications. But the XAML view must be rewritten for the WPF application.

Hope that helps.

Hi,@Sachi . As I said in my answer, WPF and UWP XAML markup and controls are different, you could look for similar functionality properties and markup to use in WPF instead of your UWP controls.

There is no CompositeTransform in WPF however there is a TransformGroup. Hence an equivalent replacement is a TransformGroup containing ScaleTransform, SkewTransform, RotateTransform and TranslateTransform in that order.

There is no ThemResource in WPF's XAML Resource. You can try to use StaticResource.
