EF Core and Domain-Driven Design
Data persistence is important to your application workflow even when focused on your domain. This course will guide you through using Entity Framework Core effectively to persist data from solutions designed using Domain-Driven Design concepts.
What you'll learn
While DDD is focused on the domain, data persistence is still important to your application workflow and if you are using EF Core, it is important to understand how EF Core maps nicely designed domain models. In this course, EF Core and Domain-Driven Design, you’ll learn to persist tactical designs of DDD with EF Core. First, you’ll explore why persistence is relevant to DDD and get a walk through of analyzing a real-world domain. Next, you’ll discover how EF Core maps by default as well as how to help EF Core with mapping aggregates. Finally, you’ll learn how to organize data related logic using skills from DDD including sharing data across bounded contexts with APIs and messaging. When you’re finished with this course, you’ll have the skills and knowledge of EF Core needed to persist your lovely domain models.
