Getting error message when i call newly created method from existing wcf service( System.ServiceModel.ActionNotSupportedException)

Question

I have existing wcf service which is working fine. I have created new operational method in the one of the servicecontract and I ref that dll into my client and calling that new operational method. when I call the new operational method, I am getting the
following error message.  old operational method is working fine when I call that.
Since my service is already there. all the binding information is present already in the config file of service and client. I didn't touch the config file since I just added new method into the servicecontract.
I am using Tcp connection.
Please help me regarding this.
Error :
{System.ServiceModel.ActionNotSupportedException: The message with Action 'http://tempuri.org/IAccountDetailService/Test' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract
mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver.  Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport,
None).

Hi Gowsiya,
Maybe the WCF forum would be better for this issue, you know that this forum is to discuss the VS IDE.
