与WCF服务共享活动

Question

I would like to share the event 'MyEvent' in the following class:

[ServiceContract]    
    public interface MyInterface
    {

     [OperationContract]
     void Start(); 

     event EventHandler<MyEventArgs> MyEvent;
    }

    public class MyEventArgs:EventArgs
    {
      public string Name{set;get;}
    }

Which Attribute should I add to MyEvent event and to the MyEventArgs class and its members?

Thanks in advance!!!

Events are not the way to communicate back to the client in WCF. In WCF you use callbacks. See http://msdn.microsoft.com/en-us/magazine/cc163537.aspx#S2 and http://msdn.microsoft.com/en-us/library/system.servicemodel.servicecontractattribute.callbackcontract.aspx for more information.
