Use mycontentpage.windows.xaml to only include the ContentPage when the platform is Windows

[AndreasReitberger]

Is it possible to build a ContentPage only if the target platform is Windows.

The reason is, the ModelViewerPage will use content which is only available on Windows (Helix Toolkit). So it will fail building for other platforms.

I know it is possible for CSharp files to use a naming like myclass.windows.cs, then it is like

#if WINDWOS
// my class...
#endif

Thanks for the help!
