That's why you take the copy.
Really appreciate your explanation, Pete ! From what you say, I infer that when you do something like:

var handler = PropertyChanged;

Then an actual copy of the underlying handler is made ? Not just a "duplicate of the pointer" ? My struggle to form some kind of practically useful "mental model" of EventHandlers and InvocationQueue ... continues, although I don't have any real problem using them, right now ... albeit my usage does not include dealing with possible threading issues, yet. What saved my read-end was learning that you can effectively switch a specific EventHandler instance in/out by doing a -= remove call which, praise be, does not throw an error if the EventHandler == null.

From now on, I believe I can summon your presence by simply invoking the names of the two Richards Smile | :)
«There is a spectrum, from "clearly desirable behaviour," to "possibly dodgy behavior that still makes some sense," to "clearly undesirable behavior." We try to make the latter into warnings or, better, errors. But stuff that is in the middle category you don’t want to restrict unless there is a clear way to work around it.» Eric Lippert, May 14, 2008
