title: Error in Nuget PM Visual Studio Express v2013
body: <p>I have not been able to resolve this error from the Nuget Package Manager.</p>
  
  <p>I have tried un-installing T4 Scaffolding and reinstall. I developed this program in Visual Studio 2012 with the 3 updates and have now migrated the program to the VS Express 2013 The program had no errors in the 2012 version. I have searched the Internet, Nuget and this site and I have not been able to resolve this. I should mention I have MvcMailer in the packages and it seems to rely on the T4 Scaffolding. And answers would be appreciated.       </p>
