title: Why don't I have SubmitChanges?
body: <p>Is this something that's been changed in MVC 3? There is no <code>SubmitChanges()</code> method anywhere and I can't figure out, I seem to have the proper namespace too (<code>System.Data.Linq</code>).</p>
  
  <p>The only thing I find is <code>SaveChanges()</code> instead. Are they the same? Or have I run into something strange here?</p>
