[Mono-dev] Cross Platform on Linux/Windows with Mono.Posix reference on Linux

To Alan's point, we did see crashes when we (unintentionally) deployed Mono.Posix.dll along with our app. Our solution was, like he said, to Not Do That, and use our Mono.Posix as a compile-time library only.
I do think it's much easier to do it this way than to have different compile targets, which (if I'm understanding correctly) is what the other suggestions all require.

Mono.Posix.dll *itself* contains no platform-specific code and is perfectly safe to copy between operating systems.
Mono.Posix.dll contains P/Invokes into “MonoPosixHelper” (libMonoPosixHelper.dylib on OS X, MonoPosixHelper.dll on Windows, etc.), and MonoPosixHelper contains operating system-specific code. It *cannot* be copied between operating systems; it’s a native library.

It’s entirely fine to include Mono.Posix.dll with your app, SO LONG AS you *also* copy and distribute MonoPosixHelper with your app.
Additionally, Mono.Posix.dll also P/Invokes other native libraries such as INTL.DLL (Mono.Unix.Catalog) and MSVCRT.DLL (Mono.Unix.Native.Stdlib), which should be usable on Windows (so long as you also distribute INTL.DLL, etc.).
