Will they continue to make F# work with Mono? or indeed do they support it right now? > > And somehow F# seems to be licensed under a very restrictive license > > In what way? I can sell programs that I write in F#. The license, "Microsoft Research Shared Source License Agreement" (http://research.microsoft.com/fsharp/fsharp-license.txt) explicitly prevents commercial redistribution of the F# sources, and that means for example that it could never be part of a free operating system like Debian or Fedora. In practical, day to day terms I'd better hope that Microsoft Research continue to produce and support new versions of F#. If one day they just abandoned it, or if they decided to drop support of Mono then I'd be up a creek without a paddle (but with a lot of software which I'd have to rewrite in another language). > > (how did they get away with that one? - Did they pay INRIA for a separate > > source license?) > > Besides legacy, F# has nothing to do with OCaml and INRIA. So F# was a separate implementation? I thought it was derived from an older version of OCaml - but with the licensing issues above I'm not about to download the source to check that. Discussion moved to caml-list. It's important to get any misunderstandings about F# resolved. Rich. -- Richard Jones Red Hat
