Using JsonConvert.SerializeObject to serialise a derived List

I have a simple class:

 public class ProductListStoredModel: List<Product>
 {
        public int NextId { get; set; }
 }

If I use:

  ProductListStoredModel stored_model = ...
  string new_json = JsonConvert.SerializeObject(stored_model);

It will happily serialise the list. However, it doesn't add 'NextId' to the JSON. Is there a simple way to do that (like adding an attribute)?

  class Program
    {
        static void Main()
        {
            ProductListStoredModel stored_model = new ProductListStoredModel();
            Product p = new Product();
            stored_model.Add(p);
            stored_model.NextId = 10;
            stored_model.Pro = stored_model[0];
            string new_json = JsonConvert.SerializeObject(stored_model);
            Console.WriteLine(new_json);
            Console.ReadLine();
        }
    }

    [JsonObject(MemberSerialization.OptIn)]
    public class ProductListStoredModel : List<Product>
    {
        //public Product[] pro { get; set; }
        [JsonProperty]
        public int NextId { get; set; }

        [JsonProperty]
        public Product Pro { get; set; }

    }

you can make an array property of product as well and can continue so on.

public Product[] Pro { get; set; }
