title: Reset Entity-Framework Migrations
body: <p>I've mucked up my migrations, I used <code>IgnoreChanges</code> on the initial migration, but now I want to delete all my migrations and start with an initial migration with all of the logic.</p>
  
  <p>When I delete the migrations in the folder and try and <code>Add-Migration</code> it doesn't generate a full file (it's empty - because I haven't made any changes since my last, but now deleted, migration).</p>
  
  <p>Is there any <em>Disable-Migrations</em> command, so I can rerun <code>Enable-Migrations</code>?</p>
