Json Deserializer en C # devuelve valores incorrectos de la respuesta de solicitud de Json

Estoy intentando devolver la respuesta Json deserializada de la siguiente https://www.supremenewyork.com/mobile_stock.json

A continuación se muestra mi código:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Text;
using System.Drawing;
using System.IO;
using System.Net.Http;
using Newtonsoft.Json;

using System.Globalization;

namespace SupremeMobileMonitor
{
    class Program
    {
        static async Task Main(string[] args)
        {
            var program = new Program();
            await program.GetItem();

        }
        // Declaring variables in the list
        static List<ItemDetail> ProductList = new List<ItemDetail>();
        List<string> productDesc = new List<string> { "new_item", "price", "category", "imageurl", "itemURL" };
        List<string> category = new List<string> { "jackets", "shirts", "tops_sweaters", "pants", "hats", "accessories", "shoes", "skate" };

        //creating a class for intializing Json Deserializer 

        public class MobileStockResponse
    {
        [JsonProperty("unique_image_url_prefixes")]
        public List<object> UniqueImageUrlPrefixes { get; set; }

        [JsonProperty("products_and_categories")]
        public Dictionary<string, List<ProductsAndCategory>> ProductsAndCategories { get; set; }

        [JsonProperty("release_date")]
        public string ReleaseDate { get; set; }

        [JsonProperty("release_week")]
        public string ReleaseWeek { get; set; }
    }
        public partial class ProductsAndCategory
        {
            [JsonProperty("name")]
            public string Name { get; set; }
            [JsonProperty("id")]
            public long Id { get; set; }
            [JsonProperty("image_url")]
            public string ImageUrl { get; set; }
            [JsonProperty("image_url_hi")]
            public string ImageUrlHi { get; set; }
            [JsonProperty("price")]
            public long Price { get; set; }
            [JsonProperty("sale_price")]
            public long SalePrice { get; set; }
            [JsonProperty("new_item")]
            public bool NewItem { get; set; }
            [JsonProperty("position")]
            public long Position { get; set; }
            [JsonProperty("category_name")]
            public string CategoryName { get; set; }


        }


        //Initializing HttpClient for Requests and po
        public async Task GetItem()
        {
            var client = new HttpClient();
            var request = new HttpRequestMessage
            {
                RequestUri = new Uri("https://www.supremenewyork.com/mobile_stock.json"),
                Method = HttpMethod.Get
            };
            var response = await client.SendAsync(request);
            var responseContent = await response.Content.ReadAsStringAsync();
            var responseObject = JsonConvert.DeserializeObject<ProductsAndCategory>(responseContent);

            Console.WriteLine(responseObject);




        }



    }
}

Cuando intento devolver un valor (ejemplo: responseObject.id), solo devolverá '0'

Cuando intento devolver la respuesta completa, devuelve "SupremeMobileMonitor.Program + ProductsAndCategory"

¿Alguna idea de por qué no puedo recuperarlo y qué estoy arruinando mi deserialización? Desafortunadamente, la categoría conocida como "nueva" en el punto final interfiere con las palabras clave de C #, por lo que elimina mi opción de usar la deserialización dinámica.
