I've been writing most of my utility code in F# for the past few months, is there anything that you guys DON'T like about it? I'm really enjoying how terse it is in comparison to C# and haven't really run into anything that's bothered me, besides Xamarin Studio being bloated.
http://fsharpforfunandprofit.com/posts/classes/ starts off with a C# vs. F# class declaration example. Particularly when you want to create a class with 3 member properties and a constructor accepting those 3 properties as parameters, you can achieve that in 4 lines of F# vs. 8 (non-curly brace) lines of C#.
This sort of conciseness is found all over the language as you keep digging deeper. I really recommend Scott Wlaschin's (link author) entire site. The best online resource for learning F#, IMO.
