I haven't tried with the latest version of Mono but, with the previous version, some useful and common libraries (e.g., FParsec) weren't fully supported. I've heard that F# support has improved in the latest version, but that it's still not complete.

I haven't tested it myself because I got tired of working around Mono issues, and just wrote a little script that sends .fsx scripts to my windows machine, runs them there, and returns the output on my linux machine. I can see why you wouldn't want to do that in a production environment, though.

I've been meaning to try this. In meantime: Only 1 critical open ticket:
