Dear biswarup88,
Well from the message I could hypotize that your environment where you run VS has different culture settings. Possible then the parsing a string as a valid DateTime fails. Get the page in which this error occurs and try to do a culture specific parsing.
You can check this or google for some more info on parsing date time using a specific culture:

Let us now if it helped.
