How to remove child one to many related records in EF code first database?

Question

Well, I have one-to-many related model:

public class Parent
{
    public int Id { get; set; }
    public string Name { get; set; }
    public ICollection<         


        

Answer 1

Try changing to

 public virtual ICollection Children { get; set; }

because virtual is needed to get lazy loading. as explained here

I think your parent.Children.clear isnt working because the Children have not been loaded
