Unless I'm mistaken, the contest was limited to supported languages. F#, ... don't appear because they weren't supported I'm not familiar with how the contest was implemented, but I would assume that if C# was supported, then any .Net language would work. It should be trivial to build a C# wrapper for your F# code, if the interface you must support can be implemented in all those other languages.
