A new version of a Haskell .NET interop layer, hs-dotnet, has just been released and is now available for download, http://haskell.forkIO.com/dotnet It lets you access .NET functionality from Haskell and vice versa. Tool support is included in this release to aid such interop. The new version includes development done since the start of the year. Apart from rewriting the internals completely to put it all on a sounder footing, this release includes proper support for .NET generic types (classes and interfaces), mapping them naturally on to Haskell parameterized types. The support for generics enables for instance mixed Haskell-.NET LINQ programming; see the distribution for examples of this along with some other interesting applications of the hs-dotnet interop layer. enjoy --sigbjorn
