title: Entity Framework error - Error 11009: Property ' ' is not mapped
body: <p>To improve an older project I am forced by the circumstances to use VS 2008 and Framework 3.5 - I have issues with the edmx showing bizarre behavior and not updating the entities as required.</p>
  
  <p>The edmx throws me the above error, but when I go to the respective table and right click it - "Update Model from Database" there is no change, the error is still there. </p>
  
  <p>If I delete the table from the diagram by selecting it and pressing del, then in the Model Browser It disappears from the .Database but when clicking "Update model from Database" I can't see i in the "Add" list, all I can do is "Refresh" the table since I still see it in the refresh list (which should not happen because I deleted it! )</p>
