  • Introducing the F# programming language (April 2007)

    "Microsoft's F# programming language is a functional language for the .NET framework that was originally developed at Microsoft Research Cambridge by Don Syme. In October 2007, the senior vice president of the developer division at Microsoft announced that F# was being officially productized to become a fully supported .NET language and professional developers were hired to create a team of around ten people to build the product version. In September 2008, Microsoft released the first Community Technology Preview (CTP), an official beta release, of the F# distribution. In December 2008, Microsoft announced that the success of this CTP had encouraged them to escalate F# and it will now be shipped as one of the core languages in Visual Studio 2010, alongside C++, C# 4.0 and VB..."
