title: Tell Entity Framework to ignore custom database tables
body: <p>Is it possible to tell Entity Framework to ignore any custom tables I add to the database. For example, say if I use the sqlmemberhipprovider in the same database as the one used for EF, can I tell EF to just ignore whatever tables I haven't already created classes for? Right now, it's giving the error </p>
  
  <p>"The model backing the 'xxx' context has changed since the database was created. Consider using Code First Migrations to update the database (<a href="http://go.microsoft.com/fwlink/?LinkId=238269" rel="nofollow">http://go.microsoft.com/fwlink/?LinkId=238269</a>). "</p>
  
  <p>I don't want EF to do anything on the extra tables it doesn't recognize.</p>
