JetBrains started work on ReSharper 4.5 recently; but, more importantly, they just made nightly builds available online. I've said it before and I'll say it again: this is the best Visual Studio add-in I've seen... and I'm not the only one who thinks so. I'm a huge productivity geek and ReSharper helps feed my addiction to speed... as in quick. JetBrains won't give you drugs. Although, ReSharper may seem like it, when you work on a machine without it. Development without ReSharper is somewhat analogous to drug withdrawals... cold sweats, lots of twitching, and wondering if you'll be able to finish in time. Okay, maybe not, but I do dread life without it.
