A couple years back I started using Emacs for some new work I was doing. It wasn't .Net at the time and so it seemed like a good took for that job. I ended up really liking Emacs and started to integrate into more of my day to day things.

Eventually I got it setup for .Net work and it actually handles rather well. It is better for Core since that is more command line friendly, but works for most of my needs. I now only open vs when I have some serious debugging and stepping through to do.

Does anyone else use tools that are more off the beaten trail? I would be interested to hear what those are.
