Thanks Robert, I expected something like that.
Is there an easy way to determine if the runtime has already been
initted? I would like to use Mono for practically all logic for my
unmanaged SO needs, yet allow for the possibility that the application
is managed. I would like to avoid requiring the app to pass some Mono
handle into the SO to do all its work, though if that's the way it is,
then that's the way it is. Then comes the issue of versioning the
runtimes, 2 corlibs being loaded, etc. Should I just stay away from
this whole thing?
Are there any complications that I should be aware of when the
SO+managed code is ready to be unload from the process?
