Last Wednesday we released VS2010 RC, and with it, the RC update for F#! The team has been hard at work getting the RC to ship-quality, and we hope that you like what you see.
Don’s blog has more info on the RC. You can also check out the F# Dev Center.
In addition, we have also released the F# Power Pack on CodePlex under the Microsoft Public License! The F# Power Pack is a set of additional tools and utilities that enrich your F# experience – be sure to check that out as well!
