Remarks

Initialize a MediaCapture object to use media frame sources by setting the SourceGroup property of the MediaCaptureInitializationSettings object to a MediaFrameSourceGroup returned by FindAllAsync and then calling MediaCapture.InitializeAsync. The key for each entry in the dictionary is the Id property of the MediaFrameSourceInfo associated with each frame source in the group.
