Though it's bit me a couple times that I now watch out for... a) In most situations I'd really rather have 3 levels - DEBUG on my dev machine, DEBUG on the dev server, RELEASE on the production server. b) Release code paths don't get tested as thoroughly until uploaded to the production server. I mean - you have to test them, but if you wrap everything in #if DEBUG directives, it can be nontrivial to run in VS on a dev system in RELEASE mode.
