Re: VS 2005 LoaderLock problem

Kevin Spencer <ke...@diespammersdietakempis.com>

Without a lot of explaning (I did this some time ago, and the references I
found are lost to me), the easiest solution to this issue is:

Use the "Debug" menu, and go to "Exceptions..."

Expand the "Managed Debugging Assistants" and uncheck the "Thrown" and
possibly "User-unhandled" boxes (if using the "Just My Code" option).

All I can remember about it right now is that there is an issue with the
Managed Debugging Assistant for "Loader Lock". I have never had any problems
as a result of turning this off.
