title: Visual Studio SSDT Database project will not display schema node on restart
body: <p>I added a project by importing from a database connection.</p>
  <p>Everything is fine until I quit VS and relaunch.</p>
  <p>All the files are present in the project directory.</p>
  <p>VS only shows the Properties and References nodes under the project node.</p>
  <p>I can find no way to display the schema node that was / should be there. Compare/update adds a 2nd copy of everything with _1 on the end of every file.</p>
  <p>Is there a fix / way to get these files in the solution explorer again  ?</p>
