title: In Setup project, difference between adding 'project output' and 'assembly'
body: <p>I am not sure what is the correct thing to add. In the Setup Project, when one clicks on "View" -> Editor" -> "File System", and then right-clicks and a pop-up appears.</p>
  
  <p>If Project A uses Project B, must I add B.dll (assembly), or the output of Project B?</p>
  
  <p>(Assuming that I have both Project A and Project B in the solution and that Project A has a reference to Project B.)</p>
