EF6 issues. Can't add new object in the database

I'm trying to use EF6 in my win form app. In my code when I'm adding a new object in the db I'm getting the null reference exception. Actually Products property in the method InitNewProducts is null. What am i doing wrong?

using System.Data.Entity;

namespace DAL
{
    public class CartContext: DbContext
    {
        public CartContext(): base("DbConnection")
        {
        }
        public DbSet<Product> Products;
    }
}

using System.Collections.Generic;

namespace DAL
{
    public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public double Price { get; set;}
    }
}

private void InitNewProducts()
{
    using (var context = new CartContext())
    {
        var product1 = new Product {Id = 1, Name = "SomeProduct1", CartItems = new List<CartItem> {new CartItem {Id = 1} } };
        context.Products.Add(product1);
        context.SaveChanges();
    }
}

Add accessors to DbSet<Product>:

public virtual DbSet<Product> Products {get; set;}
