Welcome to F# 3.0
A developer preview of F# 3.0 was made available as part of the preview-release of Visual Studio 11 announced at //build/ in Los Angeles.
F# brings a powerful, succinct, efficient and expressive language, which allows the user to write simple code to solve complex problems. F# is a productivity accelerator it is used by a growing community to solve analytical programming problems in a variety of domains, such as trading, finance, bio-informatics, blog analysis, advertising, and energy markets. To learn more about F#, visit the F# Developer Center.
With F# 3.0, the team is maintaining and expanding this vision through the addition of F# Information Rich Programming, including F# Type Providers and F# LINQ Queries.
