title: EF6/MVC5: References to Classes Not Part of DbContext
body: <p>I suddenly started receiving error messages from an MVC5 app that was previously working. Something deep in the NET libraries is complaining about certain classes (e.g., VoterInfo) "not having a key defined". Reference is also made to a DbSet called VoterInfoes.</p>
  
  <p>But here's the thing: there is not class called VoterInfo anywhere in the solution. Nor is there the other class causing an error (BallotInfo) defined anywhere in the solution.</p>
  
  <p>I've never encountered anything like this before. Why would VS2013 suddenly started defining objects for me?</p>
