There is no "as well as Moonlight" as far as 2.1 assemblies are
concerned. Mono (well mcs) itself provides the base code for some - but
the only "real" (as in shipping) code is build by Moonlight (i.e. the
raw 2.1 assemblies from mcs are unusable).

Please look at the path of the assemblies you're comparing from. I doubt
it's coming from Moonlight (at least for System.dll) since we (and our
build bots) would be unable to build Moonlight in this case.

You're likely using System.dll from 2.0 and System.Net.dll from 2.1
(e.g. a path issue). Make sure the right assemblies are being referenced
by the compiler.
