The exception thrown from the Windows Form application when trying to access the data portal in Azure is:
System.ServiceModel.Security.SecurityNegotiationException:
Secure channel cannot be opened because security negotiation with the remote endpoint has failed. This may be due to absent or incorrectly specified EndpointIdentity in the EndpointAddress used to create the channel. Please verify the EndpointIdentity specified or implied by the EndpointAddress correctly identifies the remote endpoint.
Inner exception:
System.ServiceModel.FaultException: The message with Action 'http://schemas.xmlsoap.org/ws/2005/02/trust/RST/Issue' 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).
