0x800a139e - JavaScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

This error only occurs when I run code in VS 2012 (i am running it on windows 8.1 64 bit). When I deploy on test site it works without any error but in VS 2012 it is throwing this error. This started happening around 1 month back, before that it was working fine.

I have searched a lot but this issue is not posted anywhere which is specific to VS 2012.
