Messaging system using C#

I discover the Messaging System for Unity watching the excellent tutorial of Alec Holowka (Infinite Ammo).

It's exactly what I need, but my project is in C#. Does anyone know an equivalent of this system or a solution to have the same thing in C#?

Thanks!

There is a whole section filled with messaging/event systems here:
