title: The type or namespace name 'Device' does not exist in the namespace 'System'
body: <p>I am trying to work with <a href="http://msdn.microsoft.com/en-us/library/system.device.location.geocoordinate%28v=vs.110%29.aspx" rel="noreferrer"><code>GeoCoordinate</code></a> which is meant to be supported by .Net Framework 4.5. I am working on winodws 8 and I have .Net Framework 4.5, but I keep getting <code>The type or namespace name 'Device' does not exist in the namespace 'System'</code> error. </p>
  
  <p>Any solution?</p>
