Asp.net 2 :I would like to post to a web service and get the result as json format. The method is decorated with [ResponseFormat=ResponseFormat.Json)]and it return a simple class. When I use prototype code like : asmxFile.MethodName( par1, par2,function(obj){}); the obj is json format, but If I use $.post("asmxFile/MethodName", {par1:val1, par2:val2}, function(obj) {}); the obj is not json format but has xml, and text properties containing all json memebers. What else shuld I add to my call to get json format. I tried getJson but it doesnùt call my web services. Any help would be greatly appreciated:
