title: TFS Changeset problem, files missing but present if viewed via "view history" open changeset
body: <p>having a weird problem with TFS (TFS2008). We've done a merge into our Main trunk. We've resolved the conflicts and we've checked in associating it with a single work item.</p>
  
  <p>So we have our WorkItem with a single changeset in it.</p>
  
  <p>Our build is failing because the previous version of the csproj file is being got from TFS. If I open the WorkItem and the go to links and open the changeset the csproj file is not listed. In fact no files that are "merge/edit" are listed... there are others missing the csproj is the first.</p>
  
  <p>If I do a view history on said csproj file I see the last changeset it was in. If I open that changeset (same number as associated with the work item) the csproj file is there present and correct, along with all other "merge/edit" files.</p>
  
  <p>If anyone has any ideas why this might happen and how to resolve it, it'd be much apreciated.</p>
  
  <p>Thanks</p>
