Error in updating edmx file
<p>I am getting an error when I am updating the edmx file.</p>

<blockquote>
  <p>Error 3002: Problem in Mapping Fragment starting at line 3828:
  Potential runtime violation of table  Archive's keys (Archive.UserID):
  Columns (Archive.UserID)  are mapped to EntitySet Archive's properties
  (Archive.UserID)  on the conceptual side but they do not form the
  EntitySet's key properties  (Archive.ListID, Archive.UserID).</p>
</blockquote>

<p>Any idea how to resolve this?</p>
