title: How to use background media player in Windows Phone Silverlight 8.1
body: <p>I am working on a Windows Phone application for Windows 8.1. I need to use features like Motion classes, Isolated Storage etc. As these features were not supported in Windows Phone 8.1 I went for Windows Phone Silverlight 8.1. Now I have to use BackgroundMediaPlayer in my project and Windows.Media.Playback is not supported in Windows Phone Silverlight 8.1. Is there any possible way by which i can use all the basic API's like:-</p>
  
  <p>-Microsoft.Devices.Sensors</p>
  
  <p>-Microsoft.Xna.Framework</p>
  
  <p>-System.IO.IsolatedStorage-System.Windows.Media.Imaging</p>
  
  <p>and use BackgroundMediaPlayer, Motion classes?? any help will be really useful.</p>
  
  <p>Thanks,</p>
