title: Data Conflict in LINQ
body: <p>When making changes using <code>SubmitChanges()</code>, LINQ sometimes dies with a <code>ChangeConflictException</code> exception with the error message <code>Row not found or changed</code>, without any indication of either the row that has the conflict or the fields with changes that are in conflict, when another user has changed some data in that row.</p>
  
  <p>Is there any way to determine which row has a conflict and which fields they occur in, and also is there a way of getting LINQ to ignore the issue and simply commit the data regardless?</p>
  
  <p>Additionally, does anybody know whether this exception occurs when <em>any</em> data in the row has changed, or only when data has been changed in a field that LINQ is attempting to alter?</p>
