title: 'master.dacpac' could not be resolved, because it could not be found
body: <p>I have several database references in a database project and I have had to add additional databases because I was getting the same error (but with the name of each database projects), but there is nothing at all inside my solution called <code>master.decpac</code>.</p>
  
  <p>The error is:</p>
  
  <blockquote>
    <p>The reference to external elements from the source named 'master.dacpac' could not be resolved, because no such source is loaded.</p>
  </blockquote>
  
  <p>What is <code>master.dacpac</code> and what could I do to resolve the error I'm having?</p>
  
  <p>Thanks</p>
  
  <p><strong>EDIT</strong> I have narrowed it down to just one database project. Deleting the database reference to the project will remove the error. While it isn't a viable solution, at least we know it is only one project.</p>
