It is the agreement between client and service which specifies:

[ServiceContract] - which services are exposed to the client.

[OperationContract] - which operations the client can perform on the service.

[DataContract] – which data types are passed to and from the service.

[MessageContract] - allow the service to interact directly with messages. Message contracts can be typed or untyped and are useful in interoperability cases when another party has already dictated some explicit (typically proprietary) message format.

[FaultContract] -which errors are raised by the service and how the service handles andpropagates errors to its clients.
