Luke Hoban from the Microsoft F# team is in town, and has offered to talk about F#:
This talk will introduce Microsoft's new language F#, a typed functional programming language for the .NET Framework that combines the succinctness, expressivity, and compositionality of functional programming with the runtime support, libraries, interoperability, tools, and object model of.NET. We'll take a look at why Microsoft is adding the language to the suite of those available on .NET, and at some of basic language constructs that make programming in F# a dream.
We'll be at at Microsoft's offices, 1290 Avenue of the Americas at 6:30, talk begins at 7PM.
