title: cannot add view to the edmx
body: <p>When trying to add a view to the edmx file, nothing happens.<br>
  I opened the edmx file using wxl editor and I noticed the following error:</p>
  
  <blockquote>
    <p>warning 6013: The table/view
    'CellularOrders.dbo.V_LINK' does not
    have a primary key defined and no
    valid primary key could be inferred.
    This table/view has been excluded. To
    use the entity, you will need to
    review your schema, add the correct
    keys, and uncomment it.</p>
  </blockquote>
  
  <p>(importent thing - I didn't and don't need to add the table which the view based on to the edmx. Moreover, the view is only for doing select statements on the data)</p>
  
  <p>So in the db, I updated the T_LINK table and made one of the fields that reflects on the view as primary key. And then, when I tryed again to add the view to the edmx nothing happens again.</p>
  
  <p>How can I solve this??
  Is there an option to fix this without doing anything to the table?
  Can I add another view that will somehow wrap the old view but with fixed properties?</p>
