WCF Session Configuration error - wcf

Question

i want to enable (SessionMode=SessionMode.Required) in my service, so when i have enabled it then test the service using WCF Client Test it raise the following error:
The message could not be processed. This is most likely because the action 'http://schemas.xmlsoap.org/ws/2004/09/transfer/Get' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.HTTP GET Error
URI: http://localhost:7645/PublisherService.svc

public interface IPublisher

}
So can any one help me to solve this problem.

Answer 1

remove the line
<security mode="Transport">
from your web.config file. because Transport seems to require HTTPS to encrypt credentials.
