I saw a similar question but it did not resolve my issue. I have a JSON web service in an ASMX file;

The code for the web method

        [WebMethod]         


        

Answer 1

Turns out it's not dataType that counts but

contentType: 'application/json; charset=utf-8'.  

It worked like a charm.
