The runtime engine will finese the overhead a little - it will load the DLL on 
the first reference to the method.  On the second and subsequent calls, it 
will go directly there.

Not yet. :-)  Got for it.

You can look at the "Microsoft.Win32.Win32KeyProvider" class for inspiration 
as to how to write the PInvoke logic.  You can also use 
"Environment.OSVersion" to detect if you are on Windows or Unix (If you 
aren't on Windows, then there's no point calling the PInvoke method).
