      The F# October 2009 CTP provides all the tools and resources needed to develop applications with the F# programming language.

      F# is a functional programming language for the .NET Framework. It combines the succinct, expressive and compositional style of functional programming with the runtime, libraries, interoperability, and object model of .NET.

      F# is well suited to a spectrum of development tasks - from interactive, explorative scripting to component and large-scale software development. The CTP release of F# provides further support for explorative development using F#, as well as improved Visual Studio integration to enable large-scale, tool-based software development.

      The F# CTP also includes the F# PowerPack components, which can be used with either this F# CTP release or the Visual Studio 2010 Beta2 release with integrated F# development support.
  • Supported Operating System

    Windows 7, Windows Server 2003, Windows Server 2008, Windows Server 2008 R2, Windows Vista, Windows XP

    • [ Note: A more recent F# February 2010 CTP release is now available ]

      The F# CTP is available as either an MSI or a ZIP. Windows users should install the MSI, which will install all the tools and the Visual Studio 2008 integration if Visual Studio is present on the machine. Non-Windows users can save and unpack the ZIP and read the instructions in README-fsharp.html.
