COM Server events usage in .Net Windows Service

Question

Hello Friends,
I have an requirement where I have to create a Windows Service in .Net in which I use a COM Server. This COM Server exposes some events. In my service, I registered for an event exposed by the COM Server. I build the service, installed and made it run. But when the event raised by the COM Server, I am not getting the event notification in my .Net service. I am using just the normal event handler syntax in my .Net code (+= operator). Is this the correct way of registering for COM Server events via .Net service or am I missing something here? Please through some light here.

Regards,
Sagar
