Service behavior {0} requires that the binding associated with endpoint {1} listening on {2} supports the context protocol, because the contract associated with this endpoint may require a session. Currently configured binding for this endpoint does not support the context protocol. Please modify the binding to add support for the context protocol or modify the SessionMode on the contract to NotAllowed.
