So long as one of those runtimes supports file/directory reading / writting it should be possible. I’ll let you do the research.
We have a fairly involved app written in mono that we have ported over from Windows .NET. The most significant issue we ran into had to do with support of floating point hardware in mono for the ARM processor. It was necessary to recompile mono with a patch that is out there somewhere (I’d have to look it up at this point), for certain functions in postgreql and datetime formatting to work. Also, httpwebrequest with ssl is less easygoing than it is in .NET. You need to actually have certificates present or explicitly ignore the request for them. There are probably a few other quirks of this sort, but nothing that should be a show stopper. Certainly ordinary file and directory reading and writing should be no problem, if that’s what you need.
