title: HttpPostAttribute not found?
body: <p>I just opened up a project I have done in MVC a while back, fired right up I looked at in the browser and now all of the sudden it just won't find the <code>[HttpPost]</code> &amp; <code>[HttpPostAttribute]</code>. What can be the problem?</p>
  <p>error message</p>
  <blockquote>
  <p>The type or namespace name 'HttpPost' could not be found (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  <p><strong>EDIT:</strong></p>
  <p>If I comment out the <code>[HttpPost]</code> I get that global is missing the UrlParameter and AreaRegistration?</p>
