How to instantiate uwp Windows.Media.Playback.MediaPlayer?

Question

I am trying to devlop a small example where I would use MediaCapture and MediaPlayer classes in universal windows app in order to record and play a short recording.

The following call to a constructor displays that lovely message in Visual Studio saying that there is no constructor which takes 0 arguments. The code doesn't compile therefore.

//using Windows.Media.Playback;
MediaPlayer mediaPlayer = new MediaPlayer();

Msdn clearly states that there is such a constructor on this link. On the other hand it states as well that

Is it the case here that it has changed? Is it me being dumb? How can I find out?

Answer 1

It depends on your Version. Before version 10.0.14393 you had to create background task for your player app. Instance has to be obtained thus:

MediaPlayer player = BackgroundMediaPlayer.Current;

But after anniversary update you don't need background task. You just can get new instance of player thus:

private MediaPlayer CurrentPlayer
   {
      get
      {
         if (_mediaPlayer != null) return _mediaPlayer;
         _mediaPlayer = new MediaPlayer {AutoPlay = false, AudioCategory = MediaPlayerAudioCategory.Media};
         return _mediaPlayer;
      }
   }
