Visual Haskell is a complete development environment for Haskell software, based on Microsoft's Visual Studio platform. Visual Haskell integrates with the Visual Studio editor to provide interactive features to aid Haskell development, and it enables the construction of projects consisting of multiple Haskell modules, using the Cabal building/packaging infrastructure.

Visual Haskell is a complete system in one download: it includes a full GHC installation with libraries, and various tools including Haddock, Happy, and Alex.

In order to use Visual Haskell, you need an x86 machine running Windows, and Visual Studio .NET 2003 or Visual Studio .NET 2005.
