That's good, since I bought it from Amazon and should be receiving it soon! :-D I figured something is better than nothing.

I haven't plowed through the book completely, but it doesn't seem bad.

Absolutely. I don't have a compsci or math background, so learning an "academic language" is very foreign to and difficult for me.

Mine is only basic, we were handily never taught functional programming practically either - a huge oversight. I'm waiting on documentation with a different focus too.

I've been spending some of my free time trying to learn about F# because it seems really interesting. The problem is, the existing F# tutorials SUCK. I think that the language tutorials provided by Microsoft were written by brainiacs in the Microsoft Research group, so it's not really helpful at all. For example, I read that this:
int -> int
...represents a function which takes and int and returns an int. The problem is, the author failed to mention which "int" represents the return type and which the parameter type. :| There's only one F# book out there yet, and all the reviews I've read of it say that it sucks too. Come on MS, if you're gonna publicly announce[^] that F# is on the rise, at least give us some good introductory material first!! Don't make it so f#ckin hard for us! ;)

I had the same problem when I first looked at F# some 2 years ago, but then found that F# is pretty much the same language as OCaml[^], and that one has some decent tutorials[^]

They must have been written by the VSS developers, because VSS sucks too.

I'd be surprised if the people who are creating F# and its documentation also pooped out VSS.

I'll bet if you get a good grip on Lisp in the meantime, that will help you out, since I would imagine that a lot of the ideas in F# have their roots in Lisp.

Good idea. However, Nemanja pointed out that F# is based on OCaml, and OCaml has good tutorials online. I'll probably start with those tutorials.

I remember that notation from university, but they really need to explain it. Lots of the tutorials assume that you have been taught discrete maths, and over and above that loads of the examples are hairy mathematical functions. MS really need tutorials and examples that don't assume a compsci background if they want to get traction for F#. Many of us know that pure functional programming is going to be a good solution for dealing with multiple cores but find the existing documentation very heavy going, they really need to do some functional programming for business programmers tutorials.
Required base compsci MS would go out of business. If I had a dollar for all the times I had to explain basic data structures and algorithms ...

You call that common sense? I call that conditioning. Every language I've ever worked with before, all of which are C-based, put the return type on the left side.

No, it's a clever convention. Especially when you start mixing in currying and composition. It's an algebra. :)

Hrm.. I think F# has more roots in languages such as Haskell, than in Lisp. F# seems much more pure than Lisp is, from a functional point of view.

I think most of the F# docs assume you already know another functional language like OCaml or Haskell. I haven't used OCaml much, but Haskell has some good books written for it.

Oh come now. They do this with actual products, why not continue the trend with experimental ones? Besides, it's written by a bunch of geeks. Do you think geeks document? Marc

Like others have mentioned, the documentation should state this. That said, mathematics contributes to it being this way, the doc writers must have assumed a mathematics background. C# 3 has something like this with lambdas:
var square = int i => i*i; // takes an int i, returns i * iAs a side note, I know some folks have played with WPF and F# together. A quick search reveals a few hits: XAML or F#[^]?
