Here's what I know:

1. I've heard that Don Syme has been thinking about DLR integration for F#, but nothing has been announced. 2. According to http://msdn.microsoft.com/en-us/vjsharp/default.aspx, J# is "retired" so I don't think you can expect any further versions.
3. There aren't any firm plans yet for the future of Javascript on the DLR.
4. In Visual Studio 2010, VB.NET <http://VB.NET> will have the same level of support for the DLR as C#.

Curt,

Thanks for the feedback... this is very useful. Can you elaborate on what you mean regarding "same level of support for the DLR as C#"? Does that mean that VB won't be a dynamic language, but can use the DLR (eg, to host other languages)?

Also, it seems that a language that looked similar to C# or Java (or VB for that matter) could be implemented fairly straightforwardly using the DLR tools. Does anyone know of a project like that (that doesn't need to implement all of Java/C#/VB but just the main syntax/semantics)? Any big hang-ups in implementing such a (made-up) language?

There were at least two different people working on an "IronLua", but I think that both projects are stalled.

    Hello all,

    (This might not be the right place for this question...) What are
    the current DLR languages, and their states? I'm wondering about
    those early stabs, ones under development, from MS and others. I'm
    especially interested in those that can be run cross-platform. I'd
    like to see a list of resources, like:

    Project: IronPython
    Developer: Microsoft
    URL: http://www.codeplex.com/Wiki/View.aspx?ProjectName=IronPython
    Version: 2.0
    State: mature
    DLR State: current
    License: Microsoft Public License
    Available as: source, binaries

    Project: IronRuby
    Developer: Microsoft
    URL: http://www.ironruby.net/
    Version: 1.0 alpha 2, source only
    State: active development
    DLR State: current
    License: Microsoft Public License
    Available as: source

    Project: IronScheme
    Developer: leppie
    URL: http://www.codeplex.com/IronScheme
    Version: 1.0 beta 1 (Oct 2008)
    DLR state: early adopter; actively removing DLR?
    License: Microsoft Public License
    Available as: source

    Not sure about:

    Project: Visual Basic 10
    Developer: Microsoft
    URL: http://msdn.microsoft.com/en-us/vbasic/default.aspx
    Version: 10
    State: under development?
    DLR state: planned?
    License: ?
    Available as: binaries only?

    Project: Managed JScript
    Developer: Microsoft
    URL:
    
http://blogs.msdn.com/jscript/archive/2007/05/04/managed-jscript-announced.aspx
    Version: 1
    State: mature
    DLR state: ?
    License: ?
    Available as: binaries only?

    Also, what about F# and J#?

    I'm also working with a couple of groups who are actively developing
    additional DLR languages, including a graphical data flow language,
    and a proper tail-call recursion implementation of Scheme (using
    continuation-passing style). More on those here soon, I hope.

    If you have additions or corrections to the above list, please let
    us know.

    Thanks!

    -Doug
