title: Entity framework map column which is not in old database
body: <p>I have table in a new DB which contains column 'Note'. I have old DB with the same table with the same structure which have not column 'Note'.
  I changed edmx, I added (mapped) column 'Note' from new DB. But if I want to use edmx in old DB I have error: column doest not exists...</p>
  
  <p>I try to put code to try catch, but without succesfull. Error is outside off try catch.</p>
  
  <pre><code>//---new version DB
                  try
                  {
                      vehicles = entities.Vehicle.Where(v =&gt; v.NumPlate == numPlate || v.Note == numPlate);
                  }
                  catch (Exception)
                  {
                      vehicles = entities.Vehicle.Where(v =&gt; v.NumPlate == numPlate);
                  }
                  //---old version DB
  
                  foreach (Vehicle vehicle in vehicles) //&lt;------- ERROR
  </code></pre>
  
  <p>How can I resolve?
  Thanks</p>
