namespace XamariniOSAVAudioPlayer
{
 public partial class ViewController : UIViewController
 {
  //public values

  public float MusicVolume { get; set; } = 0.5f;
  public bool MusicOn { get; set; } = true;
  protected ViewController(IntPtr handle) : base(handle)
  {
   // Note: this .ctor should not contain any initialization logic.
  }
  public override void ViewDidLoad()
  {
   base.ViewDidLoad();
   // Perform any additional setup after loading the view, typically from a nib.
  }
  partial void BtnStop_TouchUpInside(UIButton sender)
  {
   //Backgroundmusic stop
   player.Stop();
  }
  partial void BtnPlay_TouchUpInside(UIButton sender)
  {
   //call PlayMusic method
   PlayMusic();
  }
  public void PlayMusic()
  {
   NSUrl songURL;
   if (!MusicOn) return;

   //Song url from your local Resource
   songURL = new NSUrl("Sounds/song.mp3");
   NSError err;
   player = new AVAudioPlayer(songURL, "Song", out err);
   player.Volume = MusicVolume;
   player.FinishedPlaying += delegate
   {
    // backgroundMusic.Dispose(); 
    player = null;
   };

   //Background Music play
   player.Play();
  }


  public override void DidReceiveMemoryWarning()
  {
   base.DidReceiveMemoryWarning();
   // Release any cached data, images, etc that aren't in use.
  }
 }
}

Step 10

Now, go to Run option , choose Debug and the list of iPhone and iPad simulators, which are available. You can choose any one simulator and run it.
