title: Entity framework - create the csdl, ssdl and msl files
body: <p>I work with EF 4 (not with Self-tracking entities currently). I've added some columns (non of them is a key and all of the are nullable) to one of my entities, and got the <code>Number of members in conceptual type does not match with number of members on object side type</code> exception.<br>
  I've followed the accepted answer <a href="https://stackoverflow.com/questions/2096399/number-of-members-in-conceptual-type-does-not-match-with-number-of-members-on-obj">here</a> but all I got from that was that this entity does not appear in my edmx anymore. I've re-added it from DB, but I keep getting the same exception.<br>
  I think the problem is that I've copied the csdl/ssdl/msl files to my executing assembly directory. I'd like to copy the updated files, but they're not created again (they were once created in the <code>obj\Debug\edmxResourcesToEmbed</code> folder of my EF project), not even after removing them.<br>
  Any way to get those files created again?<br>
  Thanks.  </p>
  
  <p>P.S: As I don't want to publish excess amounts of code, I don't add anything yet but I'll be happy to add needed information, I'm just not sure what exactly is needed.</p>
