Remarks

A contract is a collection of operations that specifies what the endpoint communicates to the outside world. Each operation is a message exchange: for example, a request message and an associated reply message that form a request/reply message exchange.

A ContractDescription object is used to describe contracts and their operations. Within a ContractDescription, each contract operation has a corresponding OperationDescription that describes aspects of the operation, such as whether the operation is one-way or request/reply. Each OperationDescription also describes the messages that make up the operation using a collection of MessageDescription objects. ContractDescription contains a reference to an interface that defines the contract using the programming model. This interface is marked with ServiceContractAttribute, and its methods that correspond to endpoint operations are marked with OperationContractAttribute.
