DDD, CQRS and Event Sourcing in .NET

In this course you will learn how to apply the principles of Domain Driven Design, CQRS and Event Sourcing to build better systems that can meet the demands of your business.

Instead of just talking about these concepts in theory, we will learn by doing. This course contains plenty of hands-on exercises in C# that will show you alternative ways to build software. You will also learn general architecture principles and other best practices for creating better systems.

DDD, CQRS and Event Sourcing are independent techniques that you can use on their own, but together they form a powerful approach to creating modern applications.

Software that:

  • Better captures your domain and business
  • Is easier to test and validate
  • Scales better as traffic grows
  • Can evolve easier over time
  • Is easier to understand

Even if you don’t create a full-blown CQRS/ES/DDD system from scratch, this course will teach you plenty of solid ideas, patterns and principles that you can apply in your existing applications.

In the course we use .NET 5/6 and Visual Studio 2019/2022 and in the exercises you will gradually build up an application from scratch.
