Should C# event handlers be exception safe?

Question

Assuming that one event has multiple handlers, if any of event handlers throw an exception then the remaining handlers are not executed.

Does this mean that event handle

Answer 1

In an ideal world, yes. It's a good idea to try to design event handlers so that they:

• Don't throw exceptions
• Execute very quickly

Not doing so will result in unexpected side effects, since other subscribers to the event may never receive messages, or receive them very late.
