You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment. (Line numbers are included for reference only.)
01 [ServiceContract(SessionMode=SessionMode.Required)]
02 public interface IOrderManager
03 {
05 void CloseOrder();
06 }
You need to decorate the operation as the method that closes the current session. Which code segment should you insert at line 04?
A.
[OperationContract(IsInitiating=false)]
B.
[OperationContract(IsTerminating=true)]
C.
[OperationContract]
[OperationBehavior(ReleaseInstanceMode= ReleaseInstanceMode.AfterCall)]
D.
[OperationContract(IsTerminating=false)]
[OperationBehavior(ReleaseInstanceMode= ReleaseInstanceMode.AfterCall)]
Explanation:
IsTerminating: Gets or sets a value that indicates whether the service operation causes the server to close the session after the reply message, if any, is sent.http://msdn.microsoft.com/en-us/library/ms576478(v=VS.100).aspx
