Subclass creation/removal with persisted parent class?

[deuce]

I have the following simple class structure, simplified for post:

class Person
{
public int ID;
}

class Student : Person
{
public Student(Person person){}
}

The problem I am facing is when I pass in the person and assign all
the values to this object including the ID, it wants to update when I
call SaveOrUpdate. I need to save the student WITHOUT modifying the
ID of the person. So since the person class has already been
persisted, I just need the INSERT for the subclass.

On the other end of this, how would I go about removing the Student
subclass BUT leaving the person?

Use composition instead of inheritance.

I'm having the same problem. Is there any solution where I don't need
to redesign application?

Sly,

I ended up created a Role class with a subclass of Student. The
Role class points back to the Person class for traversing to that
object but is working fantastic and can be modified without affecting
the Person. When I want a Student, I ask for the Student via my
StudentRepository class and then can traverse to the Person class is
necessary.

-Good luck!
