If EventClass is specified, it must not be disabled in the COM+ catalog; if enabled in the COM+ catalog, it must be specified on the component.

Method calls on an event class are never delivered to the implementation; they are instead delivered to event subscribers.

For a list of initial property values for an instance of EventClassAttribute, see the EventClassAttribute constructor.
