title: No file was supplied for reference XXX.dacpac; deployment might fail
body: <p>I have a DacPac project that references several other dacpac projects. The referencing dacpac builds into an application directory that is harvested into a Wix Installer using Parrafin. All the referencing and referenced projects build fine. Multiple times today, when I attempted to deploy my referencing dacpac database, I got several an instance of this error per reference:</p>
  
  <p><code>No file was supplied for reference XXX.dacpac; deployment might fail.</code></p>
  
  <p>So far, I have:</p>
  
  <ul>
  <li>checked the installation directory: found none of the referenced dacpacs present.</li>
  <li>cleaned and rebuilt the dacpacs: No issues </li>
  <li>compared database project settings between these dacpacs and others that work as expected</li>
  <li>rebuilt the Wix installer again in case it was a fluke</li>
  </ul>
