Adding GlobalSystemMediaTransportControlsSessionManager to Windows.Media.Control

[johnrogers]

I'm interested in adding GlobalSystemMediaTransportControlsSessionManager to the Windows.Media.Control namespace to provide some functionality for 'Wallpaper Engine', namely the media integration feature, however, I have no clue how to add the class. On initial inspection of the dlls/windows.media.mediacontrol folder, I've found that some legacy code from Media Transport Controls is implemented but not the newer System Media Transport Controls. I would greatly appreciate any pointers on where to start updating the code.
