I need to debug a native vc++ dll used in a c# app winforms app.  The c# app
employs DllImportAttribute, and static extern int, to define the functions it
calls from the vc++ dll.
The vc++ dll is not referenced, nor does it use com to communicate, rather
it registers the windows handle with the dll and uses a WndProc override to
receive windows messages from the event.

I tried building the dll in full debug, and dropping it into the c' apps
debug directory in order to step into the dll's methods, but unfortunately I
got the following message:

LoaderLock was detected
Message: Attempting managed execution inside OS Loader lock. Do not attempt
to run managed code inside a DllMain or image initialization function since
doing so can cause the application to hang.

Can anyone provide any help as to what I need to do in order to step from
the c# app into the vc++ dll's functions.  

Thanks.
