How can I use Mono.Unix on Linux?

Question

I have a C# app originally written in Windows that I'm now running in Linux on MonoDevelop. It works fine but now I need to recognise symbolic links. I found this answer but when I add:

using Mono.Unix;

I get the error "The type or namespace name 'Unix' does not exist in the namespace 'Mono'. Are you missing an assembly reference (CS0234)?"

You need to do what the error message says. Unintuitively, Mono.Unix lives in Mono.Posix.dll, so you need to add that as reference.
