Practical Domain-Driven Design with EF Core

Explore Domain-Driven Design (DDD) and its practical implementation with Entity Framework Core in this conference talk from NDC London 2021. Delve into key DDD concepts such as bounded contexts, domain models, and encapsulation of behavior. Learn how to extract methods, avoid public setters, and leverage domain services and events. Discover techniques for moving from primitive obsession to value objects, and understand the role of repositories and units of work in DDD. Gain insights into embracing DbContext and implementing specifications with base classes and extension methods. Master the art of creating clear boundaries between different parts of your system and building a robust domain model that incorporates both behavior and data.

Intro
What is Domain-Driven Design?
What is Domain Model? An object model of the domain that incorporates both behavior and data.' - Martin Fowler
Bounded Contexts • A defined part of software where particular terms, definitions and rules apply in a consistent way Clear boundaries between different parts of the system
