CQRS is simpler than you think with C#11 and .NET 7! - Oskar Dudycz

Oskar Dudycz demonstrates how to implement CQRS simply using C# 11 and .NET 7 without unnecessary architectural complexity.

CQRS is often perceived as an over complex pattern with a lot of redundancy and ceremony. Too often it's explained as pushing towards multiple databases, eventual consistency, DDD, and Event Sourcing. In this talk, I will show that it's the opposite. During live coding, I will show how CQRS can help in tackling the layered architecture complexity. I'll build a simple but real WebAPI. Then I'll spice all of that with all the goodies from C#11 and .NET 7 to help achieve that. Records, Nullable Reference Types, Endpoints etc. The main focus will be on CQRS and pure .NET, not Event Sourcing, or DDD. Oskar is a developer, technical team leader, and architect. Oskar started a career before StackOverflow existed. For over 14 years, Oskar has been creating systems close to the business process. Oskar believes that Event-Driven Architectures and Event Sourcing are great ways to achieve that. Oskar is an active open-source developer and one of the Marten library maintainers.
