title: Operation failed, unable to locate the solution directory
body: <p>I'm new to ASP.NET and have been working through some tutorials in VS 2013. I just tried to open up Nuget by clicking on Website > Manage Nuget Packages, but got this error message: </p>
  
  <p>"Operation failed. Unable to locate solution directory. Please ensure that the solution has been saved."</p>
  
  <p>I can't seem to find anything online about how to fix this, and Nuget is definitely installed and everything is saved. Any thoughts?</p>
