title: UWP CameraCaptureUI - default camera
body: <p>Is it possible to set the default camera to use with the CameraCaptureUI API?
  On my dev tablet, the default camera is the front and I need to use the back camera.
  It seems to be no parameter in the camera application to specify the default camera.
  Also is there a way to launch the CameraCaptureUI in full screen mode?</p>
