Dealing with concurrency in applications is one of the hardest tasks we undertake as software developers. Graceful recovery from exceptions, scalability, and building distributed systems are pretty hard too. Carl Hewitt envisioned the Actor Model to tackle exactly those kinds of hard problems. In this talk we'll discuss what the Actor Model is, how messaging between actors works, and the inherent complexity cost of building a system of actors. We'll also look at some implementations of actor systems using Akka.net and C#.
