title: Entity Framework - how do I add a table back after hitting "Remove From Diagram"
body: <p>on the model.edmx diagram, I meant to delete a table, but instead clicked the "Remove From Diagram" option.  This simply took the table off of the diagram but every time I save or compile it regenerates the underlying class file.</p>
  
  <p>I thought I could add it back in and then delete it properly, but when I try to re-add the table via "Update Model from Database..." it does not appear in the list of tables able to add.</p>
  
  <p>How do I re-add a table I "Remove From Diagram"-ed back onto the model?</p>
