Remarks

Multiple apps can simultaneously acquire frames from the same MediaFrameSource, but only a single active MediaCapture instance can acquire exclusive control and modify the settings for the frame source. Set SharingMode to ExclusiveControl if you need to adjust the configuration (of any of the frame sources included the requested SourceGroup. A MediaCapture instance becomes active when a stream has been started or after a camera control value is set by using the MediaCapture.VideoDeviceController. Attempting to render active a MediaCapture instance when another controlling mode instance is already active will result in a sharing violation failure. If you only need to acquire frames without modifying the configuration, set SharingMode to SharedReadOnly.

When the SharingMode is set to SharedReadOnly, some of the MediaCaptureInitializationSettings properties can't be configured. See below table for details.
