Thetype exposes the following members.
|BeginMethod||Gets or sets the begin method of the operation.|
|Behaviors||Gets or sets the operation behaviors associated with the operation.|
|DeclaringContract||Gets or sets the contract to which the operation belongs.|
|EndMethod||Gets or sets the end method of the operation.|
|Faults||Gets a collection of the descriptions of the faults associated with the operation description.|
|IsOneWay||Gets a value that indicates whether an operation returns a reply message.|
|KnownTypes||Gets the known types associated with the operation description.|
|Messages||Gets or sets the descriptions of the messages that make up the operation.|
|Name||Gets or sets the name of the operation description.|
|SyncMethod||Gets or sets the service synchronization method of the operation description.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|

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 that describes aspects of the operation, such as whether the operation is one-way or request/reply. Each 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.
