I am a ReSharper addict. I admit it. I have this habit of upgrading my ReSharper every time JetBrains releases a new version.
Speaking of which: ReSharper 3.1 is out and ready for download.
Or you can read the release notes.
But, if you are hoping this will add C# 3.0 support…it doesn’t. That is supposed to be next month, in ReSharper 4.0. BTW, there is a small note on the web site, if you buy ReSharper 3.0 now, you will get a free upgrade to ReSharper 4.0.
