How does Entity Framework handle inheritance when using the Code-First approach?
- Joined Table
- Table-Per-Concrete Class (TPC)
- Table-Per-Hierarchy (TPH)
- Table-Per-Type (TPT)
In the Code-First approach, Entity Framework handles inheritance by defaulting to Table-Per-Hierarchy (TPH) strategy, where all classes in the inheritance hierarchy are mapped to a single table. To implement Table-Per-Concrete Class (TPC) inheritance, explicit configurations are required, specifying separate tables for each class in the hierarchy, resulting in a challenge due to maintaining relationships and ensuring data integrity across multiple tables.
