    Cite? I'm interested in seeing this tool, but where is it?

    Thanks,

    Hi Ronald --

    Yeah, shoot me, I exaggerated a bit. <g> I respect Jay's work very much, but it
    clearly shows this is a far easier task than source recovery used to be. I'm sure
    he's said as much, himself. That such a tool shows up midway through a beta1 cycle
    says a lot, IMO.

    Later... Karl

    Karl,

    You really misrepresent my position with that quote. Specifically you
    trimmed "The metadata can't be eliminated (as things like Reflection and the
    GC require it), do you think that metadata rich x86 code is magically much
    more difficult to reverse engineer than MSIL (it's not.)"

    VB6 does *not* include the level of metadata that .NET does in the resulting
    binary images.

    As more metadata is included the task of reverse engineering becomes easier
    both by hand, and to automate. The metadata is more of a problem than the
    instruction set.

    Right. :-)
