In further work on my "baffling unresolved token error" from yesterday,
I have moved to an approach of placing more code in the native .lib
file which is then called from the managed wrapper.

Unfortunately, I seem to be unable to debug the native .lib.  It is in
the same solution as my managed code but in its own project.  If I set
breakpoints in the .lib's code they are not hit and appear with the
question mark when the program is running, indicating no code match is
available.  Every obvious release/debug toggle on the .lib's project is
set to debug.

Is there something I can do to enable debugging of the native code?
Thanks!
