In Windows Communication Foundation (WCF) applications, service methods communicate processing error information using SOAP fault messages. SOAP faults are message types that are included in the metadata for a service operation and therefore create a fault contract that clients can use to make their execution more robust or interactive. Since SOAP faults are expressed to clients in XML form, they are highly interoperable.
