title: This project references NuGet package(s) that are missing on this computer
body: <p>I have an ASP.NET MVC5 application that worked yesterday and now I am getting this error when I try to build:</p>
  <blockquote>
  <p>This project references NuGet package(s) that are missing on this computer.</p>
  </blockquote>
  <p>I have the two options checked that allow nuget to automatically download and install missing packages checked / turned ON. I have also tried deleting all of the files in the packages folder and then have nuget re-download them. Also when I open nuget and look for updates it says there are none that need to be installed. I can't figure what else to do to move beyond this amazingly annoying issue.</p>
  <p>I have also enabled nuget restore by right clicking the project and selecting that option. It then added a nuget folder and three items in that folder and does nothing to resolve the problem. I've tried re-building and still get the same error.</p>
