not at work atm but recall
1) made assembly callable using Bruce method of dissemble, modify il file then reassemble dll. Don't have vs installed.
2) used regasm without /unregister and /regfile on development machine. i did specify /codebase.
however i couldn't seem to access the assembly till I installed it into GAC.
maybe I should try run regasm again as I think the dll has now moved since I installed in the gac.
will try a few things tomorrow.
