C-based language developers don't want Edit and Continue, right?
Unless they're coding on a Mac (OSX Panther release)...
Fix and continue
Waiting for single-fix turnarounds — stop app, fix bug, compile changes, link objects, run app — is unquestionably the biggest hit to your productivity. But Xcode’s fix and continue feature gives you near-instant turnaround while debugging by letting you make changes to apps while they are still running. You simply make the edits, save the code, compile it and instantly see the change take effect in your application running live in the debugger.
Flame Retardant Note: I'm not trying to start the whole EnC argument back up. I miss the hell out of it, though, and hope it gets in VS soon.
