Summary

We have learned and built different kinds of relationships supported by EF in this chapter. We started with regular one-to-one, one-to-many, and many-to-many relationships, and from there applied a few Fluent API methods to achieve relationships. Then, we covered different usages of the Fluent API on the terminologies we saw in Chapter 3, Relationships – Terminology and Conventions. Finally, we have seen the behavior of Delete operations on dependent entities if a principal entity gets deleted. These sections dealt with relationships, but never looked at validations, except where required. Let's explore them in the next chapter.
