Normally, compilers will automatically embed calls to the ComAwareEventInfo.AddEventHandler(Object, Delegate) and ComAwareEventInfo.RemoveEventHandler(Object, Delegate) methods instead of using regular add handler and remove handler methods for events. This occurs if the interface that the corresponding event is defined on needs to be embedded.

You can specify this by embedding the entire assembly that contains the interface by using the /link option on the compilers or by setting the Embed Interop Types property to True in Visual Studio.

The ComAwareEventInfo type derives from the EventInfo class and overrides the EventInfo.AddEventHandler(Object, Delegate) and EventInfo.RemoveEventHandler(Object, Delegate) methods.
