I'll be speaking about F# at the Central Ohio .NET Developers Group Sept 25, 2008. If you are in the area come check it out. Although F# is a fusion language, and does OO extremely well, I will focus mainly on F#'s functional abilities. You can't learn the language in one session, but hopefully you will walk away with more knowledge of functional concepts and how they are implemented in F#. Feel free to give me beforehand this week or next if there is anything specific you would like to see me cover.
