title: Error: SQL71564 When migrating to Azure
body: <p>I'm trying to do my first migration to Azure and I'm getting the following error:</p>
  
  <blockquote>
    <p>One or more unsupported elements were found in the schema used as part
    of a data package. Error SQL71564: Error validating element [develop]:
    The element [develop] has been orphaned from its login and cannot be
    deployed.  (Microsoft.SqlServer.Dac)</p>
  </blockquote>
  
  <p>I'm a little confused, since 'develop' is the user name we have been using for testing, nothing more, nothing less.</p>
  
  <p>Background:</p>
  
  <ul>
  <li>The current DB is running on SQL 2016 Express.</li>
  <li>I'm using Microsoft SQL Server Management Studio 2016 (just downloaded to be sure of latest version) for the migration</li>
  <li>The schema was created using Entity Framework / migrations from C# classes so nothing out of the ordinary that I can see.</li>
  <li>All tables have primary key</li>
  <li>There are no dependencies between tables (it's all done in code)</li>
  <li>I ran SQLAzureMW (5.15.6) on this DB and it found no errors (everything was green on the report).</li>
  </ul>
