My first F# program

I love C# and have some experience in other languages. I have a hobby project and have contributed to another open source project as part of GiveCampUK. I love Pluralsight and although I’m still learning, am quite passionate about DDD, CQRS and Event Sourcing. However I still like to find alternative ways to exercise the “little grey cells” and so, despite having no use for it whatsoever, I’m going to make a concerted effort to learn F#. Here’s my first attempt of something marginally useful:

let pi = 3.141592654
let area r = pi * (r * r)
let x = area 2.0

I’ve been using tryfsharp.org, which seems to be quite a neat way to get into it. I’ll probably checkout Tekpub and Pluralsight, too. I just wish I knew what it was for
