Error
=============

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

Cause:When we Create a WCF Service ,

in the Binding Property of Service  maxBufferSize="65536",maxReceivedMessageSize="65536" are default Values 

and 

Solution: Change these values to maxBufferSize="5000000",maxReceivedMessageSize="5000000" and run ..it Execute with out Error
