Answer 1

Thanks guys for all your help :)

but I have solved the above issue finally.

The problem was with the format of the string \\" which I was trying to return from server.

Invalid string

"{\\"Response\\":\\"6\\/24\\/2014 5:33:35 PM\\",\\"hoursLeft\\":0,\\"token\\":\\"\\",\\"Error\\":\\"\\",\\"IsTrialExpired\\":false}"

Valid string

{"DateTime":"24\\/06\\/2014","Error":"","IsTrialExpired":false,"Response":"","hoursLeft":0,"token":""}

on the server side I was manually converting the object into json and returning it and this was causing the issue. I just used the ResponseFormat = WebMessageFormat.Json in my WCF operation contract and it solved the issue.
