This is the best presentation I've ever seen come out of MSFT! Congrats. As a fresh CS grad, I've heard academic whispering about functional programming but have never had the opportunity nor took the initiative to dig any deeper and learn it for myself. I'm excited that a pragmatic, .NET interoperable, first-class functional language is on the way from Microsoft. Great work guys! After 20-odd years following the computer industry I've never been happier with Microsoft. F# (and Oslo) show that Microsoft is not being complacent. And after Apple's all-style-no-substance "I'm a Mac; I'm a PC" campaign I even find myself rooting for MSFT. But I'm rambling in short great work on F# and a great introductory presentation with a sprinkling of humour :).

elvistcb: yes there is:
(define (sum-of-squares nums) (fold-left + (map sqr nums)))
(sum-of-squares '(0 2 5 8))

Very great presentation. Thanks Luca. :)

The async stuff didn't work for me. In fact, neither AsyncGetResponse nor AsyncReadToEnd exist in my version (.Net 3.5 under MSVS2008). The Plot function of Graphics is also not available. Seems to me like a special library is needed...

Isn't something like this more succinct but just as expressive without losing the declarative nature?

exm.

let sumOfSquares nums = sum (each nums sqr)

sumOfSquares [0,2,5,8]

Great Presentation!
I am watchin git for the second time and coding along through the demo. However, I am getting an error in the StockAnalyzer type...

type StockAnalyzer (lprices, days) =

let prices =
        lprices
        |> Seq.map snd
        |> Seq.take days
static member GetAnalyzers (tickers,days) =
    tickers
    |> Seq.map loadPrices
    |> Seq.map (fun prices -> new StockAnalyzer (prices, days))
member s.Return =
    let lastPrice = prices |> Seq.nth 0
    let startPrice = prices |> Seq.nth (days - 1)
    lastPrice / startPrice -1.

... the last line is not working ... getting "This value is not a function and cannot be applied" error when mouseover startPrice variable. Any advice for f# newbie? I am running the 1.9.6.2 version of f# with VS integrated shell.
Thanks!

Thank you so much. So much F# in so little time. I've already had some fun with this language, and your presentation helps me to understand how to solve some practical business problems (like I do with C# and VB.NET, presently).

Kudos!

regarding the pipeline (|>) operator example: couldn't one just write Seq.sum(Seq.map(nums,sqr) and get done with it?

Wow - this the best show I've seen here so far - it even outperforms "don't fear the monads" :)
Hope to see more of this stuff around.

Thanks for the fun !

This is really really cool, exactly what I've wanted to see in regards to F#.. I've seen so many little examples that really didn't help me envisage using this every day..

let the |> fun commence

(hurr!)
