IE prompts to open or save json result from server

Question

Internet explorer in compatibility mode gets the data from the server in an ajax callback method, and pops-up a dialog if I want to save the data or open. How to get rid of

Answer 1

Even though it's not supposedly the correct way, setting the content type to text/html made IE deal with this correctly for me:

return Json(result, "text/html");

Works in all the version that F12 tools gives you in IE9.
