In this video, we will discuss implementing Table Per Type (TPT) inheritance in entity framework with code first approach. This is continuation to Part 20, where we discussed implementing Table Per Type inheritance with database first approach. Please watch Part 20 before proceeding.

In TPT inheritance one database table per type is used to store data for the respective entity types in the inheritance hierarchy.

By default Entity Framework creates ONE TABLE for all the entity types in the inheritance hierarchy

To have a table created for each entity type in the inheritance hierarchy use Table attribute

Fluent API can also be used to do the table mapping by overriding OnModelCreating() method
