Before some day I have posted a blog about Entity Framework code first and Inheritance – Table per type and this post in next in series with that.
In previous post we have learned about how entity framework code first handles inheritance and in this part we are going to extend this and modify some of code of the code of data context to see how its creates a “Table per Hierarchy”.
We’re going to use same code as previous post just going to change EDataContext code like below.
If you see this code carefully and compare is with previous post. The only difference is persons property. That will force Entity Framework to create a single table for inheritance hierarchy. Now we are going to run this application again and see how it creates table. It will create only one table like this.

public class EDataContext : DbContext
{
public EDataContext() : base("MyConnectionString")
{
}
public IDbSet<Customer> Customers { get; set; }
public IDbSet<Employee> Employees { get; set; }
public IDbSet<Person> Persons { get; set; }
}
