Understanding CQRS and Event Sourcing in .NET with a practical example using a simple banking application to explain these key concepts in software design. Combining CQRS and Event Sourcing can make applications more robust, reliable, and easier to understand, and it gives us a perfect, automatic audit log — a history of every action taken in the application. In this article, we’re going to explore these ideas further, using a simple banking application as an example, we’ll see how each deposit or withdrawal can be recorded as an event, and how the current balance can be calculated by replaying these events, and then we’ll implement this in .NET to give you a practical example. So, let’s get started! Understanding the Basics
