EF Inserting Duplicate Parent Objects

Question

I have two classes:

public class Foo
{
    public int FooId {get;set;}
    public virtual ICollection Bars {get;set;}
}

public class Bar
{
    pu         


        

Answer 1

I think that you are approaching the problem in the wrong way. You want to add the new Bar object to your existing foo object instead of the other way round:

var foo = from f in context.Foos
          where f.FooId == 1
          select f;

var bar = new Bar();
foo.Bars.Add(bar);

context.SaveChanges();
