An existing connection was forcibly closed by the remote host

Question

I am working with a commercial application which is throwing a SocketException with the message,

An existing connection was forcibly closed by the rem

Answer 1

I've got this exception because of circular reference in entity.In entity that look like

public class Catalog
{
    public int Id { get; set; }
    public int ParentId { get; set; }
    public Catalog Parent { get; set; }
    public ICollection ChildCatalogs { get; set; }
}

I added [IgnoreDataMemberAttribute] to the Parent property. And that solved the problem.
