As a C# developer, F# is something I long to learn. I heard about F# until I had to adjust some build script which I thought is elegant [1]. I did try some F# tutorials at free time, but nothing that would make me comfortable and "click" on how to write functional code.

But I long to bring some improvements to code correctness that can be statically checked by embracing immutability, pattern matching with discriminated unions where compiler ensures you have handled all cases, typing system which makes illegal state impossible... those are just some features I spotted could be very useful. On top of that, F# code seems so much shorter.
