I know C#. I'm pretty sure Sausage declared C# "inferior" to C++ and stopped his work on EOSERV#. Apparently Addison's version is nothing like EOSERV#, it just used some of Sausages C# work as a base for what he released.
Considering the fact that Addison's release is a bit behind Sausages (in pretty much everything), I doubt people are going to use it in place of eoserv until it catches up (I think it's awesome but I'd much rather use a more complete emulator for now ^.^)
