Hey, sorry for not having brought this to mono-devel until now, but I
was curious to the answer to the above. However, nobody has answered
but, anyway, today I've just seen a commit in the runtime that may be
related to this issue:

http://lists.ximian.com/pipermail/mono-patches/2008-May/117918.html

Zoltan, can we then consider that Mono mimics .NET in this aspect:?

Is there a bugzilla bug open for this?

FYI, the original thread:
http://groups.google.com/group/gendarme/browse_thread/thread/b46d1ddc3a2d8fb9#msg_9b9c2989cedb4c34

Thanks!
