ASP.NET MVC 2.0 JsonRequestBehavior Global Setting

Question

ASP.NET MVC 2.0 will now, by default, throw an exception when an action attempts to return JSON in response to a GET request. I know this can be overridden on a method by method

Answer 1

MVC 2 block Json for GET requests for security reasons. If you want to override that behavior, check out the overload for Json that accepts a JsonRequestBehavior parameter.

public ActionResult Index()

{

   return Json(data, JsonRequestBehavior.AllowGet)

}
