Can any F# users point me towards a guide on getting started with F# and Mono on OS X? Just enough to get a simple build chain set up and get started learning the language.
http://fsharp.org/use/mac/ is probably a good place to start - if it doesn't work for you for any reason, do please complain - the community is really active in trying to make everything better! (The general section on cross-platform development may also be helpful - perhaps more when you've got a little way in!)
Additionally, there's an F# room on http://fpchat.com/ (a Slack group dedicated to functional programming) and you'd be more than welcome to come and ask questions there too - I recommend that venue in particular as it's very active at the moment.
Hopefully that's enough to have a play - reply here if I can help at all too.
As per language Expert F# from Apress by Don Syme et. all is a pretty solid practically oriented introduction. As for how to use the language most Ocaml and ML oriented books should offer hints. F# is a bit more extensive of course but how the language originally appeared it was "Ocaml for .Net".
