title: Windows Phone - Confused about background music
body: <p>In Windows Phone project I can play music in background using:</p>
  
  <p>Xaml:</p>
  
  <pre><code>&lt;MediaElement x:Name="mediaplayer"/&gt;
  </code></pre>
  
  <p>C#:</p>
  
  <pre><code> mediaplayer.Source = new Uri("Woodkid_IRON_AssassinsCreed.mp3", UriKind.Relative);
   mediaplayer.Play();
  </code></pre>
  
  <p>But in msdn Microsoft says this: <a href="http://msdn.microsoft.com/en-us/library/hh202978%28v=vs.92%29.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/hh202978%28v=vs.92%29.aspx</a></p>
  
  <p>What is the difference? Thanks.</p>
