I have the following class

public class Person
{
    private IList<Person> _children;

    public IEnumerable<Person> Children { get; }

    public void AddChild(Person child)
    {
        // Some business logic and adding to the internal list
    }
}

What changes would I have to make for NHibenrate to be able to persist the Child collection (apart from making everything virtual, I know that one).

Do I have to add a setter to the children property which does something like a _children.Clear(); _children.AddRange(value). Currently the model expresses my intent quite nicely but I'm not sure how much alteration is need for NH to be able to help me out with persistence.
