Entity Framework many to parent and child relationship

Question

I have two entities A and B with the following relationship:

• A has 0 or more B
• B has 1 parent A
• B has 1 child A

I don't know how to implement this relationship (navigation properties, Fluent API...)

Answer 1

I'm ac# writer, but I thinck you get the picture ?

class A {
    public List<B> possibleBList {get;set;}
} 

class B {
    public A Parent {get;set;}
    public A Child {get;set;}
}
