JustePort + Fedora?

[chuchII]

hey guys, did a quick search before posting but didn't find anything.

has anyone tried using "JustePort" (http://nanocrew.net/software/justeport/) or attempted to stream music to an apple airport express in fedora?
i've found all sorts of posts elsewhere and followed instructions but after compiling i get a "cannot execute binary file" message when i attempt to use it.

compiles using this command:
mcs -out:JustePort.exe *.cs

got 11 warnings:
