How to get rid of validation warnings

The complete warning is Validation (): Element 'html' occurs too few times

This is for a JSON view, which you might guess returns a JSON result and hence no html.

From stackoverflow

• ASP.NET MVC has the ability to return JSON data as a proper json response. It seems you're using HTTP response which expects HTML to exist in it.

  Here is an example of using JSON.NET to build a JSON ActionResult.
