Hands-On Domain-Driven Design with .NET Core

By: Alexey Zimarev

Overview of this book

Developers across the world are rapidly adopting DDD principles to deliver powerful results when writing software that deals with complex business requirements. This book will guide you in involving business stakeholders when choosing the software you are planning to build for them. By figuring out the temporal nature of behavior-driven domain models, you will be able to build leaner, more agile, and modular systems. You’ll begin by uncovering domain complexity and learn how to capture the behavioral aspects of the domain language. You will then learn about EventStorming and advance to creating a new project in .NET Core 2.1; you’ll also and write some code to transfer your events from sticky notes to C#. The book will show you how to use aggregates to handle commands and produce events. As you progress, you’ll get to grips with Bounded Contexts, Context Map, Event Sourcing, and CQRS. After translating domain models into executable C# code, you will create a frontend for your application using Vue.js. In addition to this, you’ll learn how to refactor your code and cover event versioning and migration essentials. By the end of this DDD book, you will have gained the confidence to implement the DDD approach in your organization and be able to explore new techniques that complement what you’ve learned from the book.

There is not much literature about Event Sourcing available at the moment, but I can recommend watching a couple of talks by Greg Young, who coined the term CQRS and opened up Event Sourcing to the world:

If you were already exploring this topic, you might have encountered some blog posts about the dark side of Event Sourcing, which mainly involves issues with event versions and eventual consistency. We'll be covering eventual consistency in the next chapter, and we'll learn even touch upon the versioning of events briefly; for more in-depth coverage of the event versions topic, refer to Greg's book:
