Unable to mock assynchronous service behaviour with Rhyno mock

I try to Mock (with Rhyno mock) the behaviour of a assynchronous service.

Here is an example: I got a service with one methode called 开发者_如何转开发void GetServerState(). As this method is assynchronous, it is void but when it's called, it'll call the proxies and the call an event GetServerStateCompleted(object,eventargs). At this point I hope everybody still follow me ;-)

now, let have a look at the mock (wich is infact a stub, but never mind)

public class MyStub
{
 protected MockRepository MockRepository {get;set;}
 public IMyService MyService {get;set;} //the service with GetServerState() Method
 protected delegate void DelegateVoid(); //for easy writting

 public MyStub()
 {
   MockRepository = new MockRepository ();
   MyService = MockRepository.Stub<IMyService >();

   //And now, let's try to mock the behaviour
   MyService.Stub(sm => sm.GetServerState())
                .IgnoreArguments()
                .Do((DelegateVoid)GetServerStateCompletedBehaviour);
 }

 //the method that should be launched when someone call GetServerState on the Stub
 protected void GetServerStateCompletedBehaviour()
 {
  MyService.Raise(x=>x.GetServerStateCompleted+=null,MyService,new EventArgs());
 }
}

//And here is how I would like to use it
[TestMethod]
void Test()
{
 try
 {
  IMyService Stub = new MyStub().MyService;
  Stub += new EventHandler(EventMethod);
  Stub.GetServerState();
  Assert.Fail();
 }
 catch(MyException){}
}

void EventMethod(Object sender, EventArgs e)
{
 Throw new MyException();
}

As everything seems right for me, this code doesn't work at all. Does someone has a begin of explanation for why it should not work ?

thx,

I found what was wrong:

public MyStub()
 {
   MockRepository = new MockRepository ();
   //MyService = MockRepository.Stub<IMyService >(); //Stupid Stupid Stupid !!!
   MyService = MockRepository.GenerateStub<IMyService >();

   //And now, let's try to mock the behaviour
   MyService.Stub(sm => sm.GetServerState())
                .IgnoreArguments()
                .Do((DelegateVoid)GetServerStateCompletedBehaviour);
 }
