Can a client contract send a SOAP fault?

In the case of duplex clients, client contracts can also send SOAP faults back to a service. In either case, you can use the default service exception behaviors, or you can explicitly control whether—and how—exceptions are mapped to fault messages. Two types of SOAP faults can be sent: declared and undeclared.
