Hello CodeDOM -- building C# and F# code from F#

A five-finger exercise in CodeDOM using the "Hello World" example from F# -- more interesting stuff to follow later:

which yields up

which isn't StyleCop compliant, but is otherwise well formatted; and

which is a little idiosyncratic; the GUID-named types seem to be there in case of need from some construct that is not actually used in this simple example.
