title: EF with only a subset of existing tables
body: <p>I got an existing database with many tables which are accessed using stored procedures only (no O/RM). I'd like to create new tables in this database using Entity Framework and the Code First approach. </p>
  
  <p>Do all the tables in my existing database need to be modelized in my Entity Framework classes? Will I be able to hand-code only the new classes I need in my <code>DbContext</code>? Other tables really need to stay untouched and away from O/RM for the moment.</p>
  
  <p><em><strong>Note:</strong> I'm going to be using the latest EF5.</em></p>
