Reactive Programming for .NET Developers

Implementing event sourcing with Rx

Event Sourcing (ES) is a software design that requires the persistence of events instead of results. In the Programming experience section of Chapter 1 , First Steps Toward Reactive Programming, we had the opportunity to understand how to persist data in a reactive way. Even though this is not mandatory using ES when programming reactive, this is the most natural way of dealing with data persistence from an observable sequence.
