title: add table to DbContext from existing database?
body: <p>Using the wizard, I created a DbContext from an existing database and only selected one table to be pulled in. However now I need to add additional tables from that database to the Entity Model.</p>
  
  <p>What is the easiest way to add more tables from an existing database to a context that I have already created and to also generate the respective models for those tables?</p>
