Different variations of the Chain of Responsibility pattern can be found in middleware like OWIN and ASP.NET Core. They all share a common approach: nesting functions inside functions, also known as functional composition. In this talk, we’ll build the Chain of Responsibility from scratch, apply it to a message pump for a service bus library and combine it with Async / Await to unleash the full power of asynchronous I/O. 

Join this talk to learn how async and recursion plays together. Discover how composition allows changing behavior at runtime. Finally, float state into your Chain of Responsibility so that you don’t sacrifice thread safety. Break the Chain of Responsibility with me.
