Not on Xamarin but on net framework 4.8:

ensure you have ref to System.Windows ..... but also to Presentation framework! nice joke @microsoft!

<Reference Include="PresentationFramework" />
<Reference Include="System.Windows" />

That's because you're missing these .dll

The recommended steps to get access to UWP APIs are listed in the dedicated blog post on Windows Blog. Basically you can take two approaches: add the references to UWP dlls and winmd files manually or use the UwpDesktop NuGet package that will take care of this for you automatically.

For more details, you can check: How do I get access to Windows.Storage namespace?
