body: <p>How can I delete a SQL LocalDB database that has had its files delete?</p>
  <p>Dropping the database yields this message:</p>
  <blockquote>
  <p>Unable to open the physical file &quot;C:\Users\Public\Documents\LocalDB.Tests.3d0d7339-7cf2-45fe-a83b-b5079112ab80.mdf&quot;. Operating system error 2: &quot;2(The system cannot find the file specified.)&quot;.</p>
  <p>File activation failure. The physical file name &quot;C:\Users\Public\Documents\LocalDB.Tests.3d0d7339-7cf2-45fe-a83b-b5079112ab80_log.ldf&quot; may be incorrect.</p>

  <p>Running <code>master.sp_databases</code> actually doesn't show them, but the Management Studio does.</p>
