Не удается десериализовать класс контейнер

Имеется небольшая библиотека классов. Сериализовать в json удается без проблем. А вот при десериализации возникает исключение Newtonsoft.Json.JsonSerializationException: "Cannot create and populate list type BooksLib.Bookstore`1[BooksLib.Product]. Path '', line 1, position 1.".

  public class Product : IComparable<Product>
{

    /// <summary>
    /// Название
    /// </summary>
    public string Title
    {
       ...
    }
    public override string ToString()
    {
        return $"Price = {Price:f2}";
    }
    
    public static explicit operator double(Product product)
    {
        return product.Price;
    }

    public int CompareTo(Product other) => Price.CompareTo(other.Price);

    public Product(double price, string title)
    {
        Price = price;
        Title = title;
    }
   
}

}

    public Book(double price, string title, short numberOfPages, short year, double rating):base(price,title)
    {
        NumberOfPages = numberOfPages;
        Year = year;
        Rating = rating;
    }
