VS2005 Errors when creating .aspx pages that retrun XML or JSON

I kept getting this on a page that did nothing but reference a code behind.

Validation(): Element 'html' occurs too few times.

This is because VS2005 is performing HTML validation by default. Yuk. You can turn this off by going to:

• Tools --> Options --> Text Editor --> HTML --> Validation
• Uncheck the "Show Errors" checkbox

Voila!
