How to debug F # / Nemerle mono application under Linux?

I recently discovered Nemerle and F #, but I cannot find a way to debug my applications. MonoDevelop 2.6 lacks support for Nemerle and F # errors, 2.4.2 and earlier due to the new gnome-sharp lib installed (I use the updated version of Arch Linux kernel-3.0 64-bit). The mono debugger at the command line refuses to start saying that "the platform is not supported." So few questions about this situation:

Is it possible to debug mono applications using gdb without going to the low level (inside vm or so)? How convenient is it to use F # REPL for interactive development without a debugger (compared to Common Lisp or Haskell GHCi)?

I use F # Interactive environment to write F # code most of the time. Even with Visual Studio, the F # Interactive environment does not (reasonably) support debugging, so I mainly rely on the ability to easily run something interactively and see if it works - if it’s not, it’s usually easy to break down into sub-components which can also be tried interactively. The great thing about F # Interactive, compared to, for example, GHCi, is that you can use it to evaluate almost anything - including type declarations.

The F # plugin for MonoDevelop 2.4 does not currently support debugging compiled F # applications. I was able to use the Mono debugger command line ( mdb , I think), but it was on a 32-bit system.

I'm not sure why MonoDevelop doesn’t select F # debugging symbols correctly, so this is most likely some basic error. There are several poeple working on the F # plugin for MD 2.6, so hopefully will be available soon. If someone wants to investigate why debugging doesn't work, that would be great ...

Nemerle has excellent Windows IDE support with Visual Studio and #Develop, better than F #, but as far as I know, there is nothing for Linux.

You can easily debug Nemerle in MonoDevelop. Just convert pdb to mono using the pdb2mdb tool: http://www.mono-project.com/Guide:Debugger Than just debug your application and you will get the correct locations.

I even managed to debug the Nemerle compiler using this trick.

About Linux and Nemerle: Nemerle got Vim bindings, Kwrite / Kate and some other editors got Nemerle support. You can also add a compiler option for any editors on Linux. Nemerle compiler just works!

Support for Nemerle MonoDevelop in development, but very slow. F # got obsolete MonodeVelop support, as @Tomas said, but what about the new MonoDevelop? Power Supply? F # 3? I think so.

Nemerle is an OpenSource project. And I'm not sure about F # 3. I like F #, but it's always Microsoft's hand. You can try both.
