Event sourcing often sounds complex, but at its core it is a simple and powerful pattern. In this talk we introduce the fundamentals of event sourcing in a way that is easy to understand, then take you step by step through a practical approach to implementing it using EF Core.

You will see how to model events, persist them effectively, and use them to rebuild state. From there we explore real world capabilities that event sourcing unlocks, including time traveling through an aggregate’s history, full traceability of how and why state changed, and inline projections that keep your read models up to date without complicated infrastructure.

All concepts are demonstrated with EF Core to show that event sourcing does not require heavy frameworks or specialized tooling. By the end of the session, you will have a clear path to adopting event sourcing in your .NET applications using libraries and patterns you already know.
