Where is SoapAction configured in WCF Client?

Question

I need my wcf client to communicate with the service with a blank SoapAction because the service is configured to dispatch the operation by body of the soap message. And the operation contract is decorated as below so it will not require soap action. I guess WCF sends a soapaction by default. Is there any option in wcf client to send a blank soapaction? Thanks for any help!

[OperationContract(Action="")]

Answer 1

use the same OperationContract attribute on your client code, ie reference.cs. More details here .
