Recently I had to work on an older project where the solution and all contained projects were targeted to x32 platform. I kept on trying to copy Oracle.DataAccess.dll and all other suggested Oracle files on all the places, but hit the wall every time.

Eight hours is a long time for the bulb to light up. No wonder I always have to slog at work :).
