Actor Programming Model with Akka.NET

Akka is a set of open-source libraries for designing scalable, resilient systems that span processor cores and networks. Akka allows you to focus on meeting business needs instead of writing low-level code to provide reliable behavior, fault tolerance, and high-performance. Akka uses actor programming model         (https://en.wikipedia.org/wiki/Actor_model).
 
Akka.NET (http://getakka.net/) is a direct port of Akka (http://akka.io/ ) which is made up of a couple of system level actors (which are not within your control, they are part of Akka.NET). These top-level actors are known as "Guardians". You never really deal with these directly. Please have a look into their materials here, https://github.com/petabridge/akka-bootcamp.
