runtime: [Xamarin.Android] System.PlatformNotSupportedException: System.Runtime.Caching is not supported on this platform

Hi,

I have a class library (.Net Standard) that uses System.Runtime.Caching, I want to use this class library in my Xamarin.Android project, but I got System.PlatformNotSupportedException exception.

Is there any plan to fix this, so we can use System.Runtime.Caching in Xamarin?

Thanks.
