实体框架数据库优先-模型中的继承问题

Question

I'm facing some problems working with EF DB First. Say I've got:

• A table Person
• A table Student with a foreign key pointing to Person
• A table Teacher with a foreign key pointing to Person

The model created from the database generates the next classes:

public class Person{
  this.Student= new HashSet<Student>();
  this.Teacher= new HashSet<Teacher>(); 
}

public class Student{}
public class Teacher{}

And what I'd really like to see is

public class Person{}
public class Student:Person{}
public class Teacher:Person{}

Is there any convention over configuration or anything I'm missing to get the inherited classes ?

UPDATE

Classes are generated in such a way because the model specifies these associations between Person, Teacher and Student. My question should be then... Is there any way to create a model from a DB using EF so that the model contains classes that inherit from other ones?

Answer 1

You're looking for Table-per-Type (TPT) mapping. Try the solution here:

Entity Framework DB-First, implement inheritance
