What's F#?

F# is a statically typed functional programming language that targets the .NET framework. It shares a common core language with OCaml, another popular functional programming language, and draws ideas from many other programming languages, including Haskell, Erlang, and C#. In a nutshell this means that F# is a programming language that has a nice succinct syntax that feels a bit like scripting as we are able to execute the code interactively but has all the type safety and performance of a compiled language. This article is not indented to be an introduction to F#, but there are many resources on the web intended to make learning F# easy. See "F# Resources" later on in the article for a list of these.
