Oh no argument on this at all, though I haven't touched .NET in several years, since I no longer have a job doing F# (though if anyone here is hiring for it please contact me!).

Even still I don't know that a benchmarking tool would be helpful in this particular case, at least at a micro level; I think you'd mostly be benchmarking the scheduler more than your actual code. At a more macro scale, however, like benchmarking the processing of 10,000 items it would probably still be useful.
