F# - Tutorial 1 - Getting Started and Hello World

recently i have been looking into F#, a rich and purely functional programming language now supported by the .NET framework and developed within the MS research centre.
F# is based on older functional languages such as: Haskell and OCML. Haskell Curry is an infamous mathematician and logistician and this is where the roots of this language originate from...

F# can be run as a standard installer from the research centre website.. or it can be integrated into Visual Studio 2008 by downloading the MSI installer. The latest release is "September 2008 CTP"

Lets have a little look at a simple Hello World application...

This sample Hello World application is the keyhole to many F# adventures. Like many other languages, the foundations begin with a Hello World example!

// Set the compilation warning to light mode; pronounced: "Hash Light".

#light

// Output Hello World!

System.Console.WriteLine("Hello World")

// Stop console from closing

System.Console.ReadKey(true)
