Problems firing events in a remote object

I've created a .Net remoting singleton object and am trying to get it to raise events that the client can sunbsribe to. The object needs to be completely independent of the clients so I have used an interface rather than copying the object's assembly to each client. I have successfully manged to get the client to subscribe but unfortunately am left with the problem that the object won't raise the events. I have defined a deligate like this (outside of any classes): [Serializable] public delegate void MyHandler(); I have defined the event in both the remote object class and the interface: public event MyHandler MyEvent; Finally I have a mthod to raise the event: protected virtual void OnMyEvent() { if (MyEvent != null) { MyEvent(); } } When having troubles I added tracing. it turns out that the OnMyEvent method is called but the if statement always returns false and the event is not raised. Anyone any thoughts as to why?
