Entity Framework Code First Conventions Foreign Key Convention
Example
If class A is in relationship with class B and class B has property with the same name and type as the primary key of A, then EF automatically assumes that property is foreign key.
public class Department
{
public int DepartmentId { set; get; }
public string Name { set; get; }
public virtual ICollection<Person> Staff { set; get; }
}
public class Person
{
public int Id { set; get; }
public string Name { set; get; }
public decimal Salary { set; get; }
public int DepartmentId { set; get; }
public virtual Department Department { set; get; }
}
In this case DepartmentId is foreign key without explicit specification.
