Get started with Event Sourcing and CQRS in .NET

Event Sourcing is a persistence design pattern. It is often mentioned alongside CQRS and DDD. In short, it is the practice of storing the events that lead up to the current state instead of storing the state itself, as one would do in a CRUD system with a normalized database. The assumption is that it is always possible to re-create the state from the events, but not the other way around. Especially when Event Sourcing is combined with CQRS architecture, it enables a whole new way of thinking about data in your applications. It enables point-in-time data and the possibility to process old events against new features retroactively.

In this course, the Event Sourcing principles and patterns are introduced, and we build an entire CQRS application from scratch to demonstrate how things piece together. We are not using a ready-made framework for this, but we are trying to take away the magic by building our own. At the end of this course, you should be familiar with event sourcing and how it fits with CQRS architecture.
