UrhoSharp (3D for Xamarin) crashes in the Sample constructor

From what I googled, I could not find solution. UrhoSharp GIT, is solution built with VS2015. I created new Xamarin mobile platform solution. Copied the relevant files over from sample UrhoSharp project. Then ran the Windows(UWP) propject. it crashes.

(I did it this way as there were too many issues with building the sample project that was created in VS2015)

 protected Sample(ApplicationOptions options) : base(options) { }



      Throws an exception.
      System.Exception
      HResult=0x80131500
        Message=Implementation assembly (iOS, Android or Desktop) is not           referenced
        Source=UrhoSharp
         at Urho.UrhoPlatformInitializer.DefaultInit()

Try to update to latest UrhoSharp package (1.9.67 at this moment), clean and rebuild the whole solution. It helped in my case.
