Yes,no,no is correct. The methods in a delegate are not guaranteed to be called in the same order as they were added.

A multicast delegate will be called in the same order it was added to the delegate. while if any of the delegate is added more than once, then it will also be called more than once. The answer is YES, YES, NO

You can override this behavior with GetInvocationList. If you wrap each delegate call in Task.Run(...), then order is not guaranteed.

yes, yes, no, delegates that are subscribed to an event are executed synchronously, the even't get's all subscribers with SendMessage.GetInvocationList() and execute them in the order they were added to the list.
