title: Copy dll modified in post-build to obj folder
body: <p>Is there a way to get a dll updated in a post-build-event copied into the <strong><em>/obj</em></strong> folder?</p>
  
  <p>Modifying the dll (to embed some generated files) in the post-build works fine, but after a ReBuild, the <strong><em>/obj</em></strong> folder always contains the 'old' dll (before the post-build event is triggered). </p>
  
  <p>This causes problems when building other projects (which seem to use the 'wrong' dll from <strong><em>/obj</em></strong> folder in some cases).</p>
  
  <p>Can this be done automatically, or is it only possibly via another post-build-command to copy the dll by hand?</p>
