title: ASP.NET System.Anything is not defined
body: <p>I ran Debugging and got a ton of &quot;is not defined&quot; errors in all the namespaces under System. The System and System.Web references are in the References folder.</p>
  <p>Trying to back track the things I've changed since the last debug, I reduced my root namespace from the default to a three letter abbreviation. Changing it back didn't do anything. Everything else I've been working on has been individual pages.</p>
  <p>Most (not all) of the errors go away if I add Global.System to all the namespaces or if I reduce them to the child namespace. i.e. these don't throw errors:</p>
  <blockquote>
  <p>Global.System.Web.UI.Page</p>
  <p>Page</p>
  </blockquote>
  <p>But this does:</p>
  <blockquote>
  <p>System.Web.UI.Page</p>
  </blockquote>
