title: Cannot find type System.SystemException in module mscorlib.dll when reference to Microsoft.Phone in Windows Phone 8.1 app template
body: <p>Microsoft just released Windows App 8.1 with combination of Windows 8.1 and Windows Phone 8.1, so you can create a universal app. However, it gives me a trouble to add Microsoft.Phone 8.1 assembly to project reference. </p>
  
  <p>Here is what I did (in Visual Studio 2013, with Rc2 installed)
  1> Create New project from Visual C#->Store Apps -> Windows Phone Apps. 
  2> Added Microsoft.Phone from this location: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\WindowsPhone\v8.1</p>
  
  <p>3> Now, do a build, I see the following Error: "Cannot find type System.SystemException in module mscorilib.dll" </p>
  
  <p>Anyone has the similar experience? any solutions?</p>
  
  <p>Thanks </p>
