title: Metadata file ... could not be found error when building projects
body: <p>Every time I start Visual Studio 2008, the first time I try to run the project I get the error CS0006 The metadata file ... could not be found. If I do a rebuild of the complete solution it works.</p>
  
  <p>Some information about the solution:</p>
  
  <ul>
  <li><p>I'm building in debug mode and Visual Studio complains about not finding dll:s in the release folder.</p></li>
  <li><p>The projects Visual Studio complains about are used by many other projects in the solution.</p></li>
  <li><p>I have changed the default output path of all projects to a ......\build\debug\ProjectName and ......\build\release\ProjectName respectively. (Just to get all build files in one directory)</p></li>
  <li><p>I have the same problem with a another solution. </p></li>
  <li><p>The solution was created from scratch.</p></li>
  <li><p>There are 9 projects in the solution. One WPF and 8 class libraries using dotnet 3.5.</p></li>
  </ul>
  
  <p>Any ideas on what is causing this problem?</p>
