 The unit test status when replacing the .NET Framework based assemblies with their PCL analogues should give an indication of the current completeness of the porting 
 of the non-imaging assemblies.

 The other 2 failed tests are due to insufficient unit test formulations, see [Issue Report 84](https://code.google.com/p/accord/issues/detail?id=84).
 
 Thus, the Portable Accord class libraries now seem to be working completely as expected.

+Note! The *Audio* related libraries are currently only functional when using the PCL libraries in a .NET 4.5 project. Support on Windows Phone and Store is not yet implemented.
