Complete code for PizzaModel class

Your Pizza.cshtml.cs file should look like this:

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;
using RazorPagesPizza.Models;
using RazorPagesPizza.Services;

namespace RazorPagesPizza.Pages
{
    public class PizzaModel : PageModel
    {
        public List<Pizza> pizzas = new();
        [BindProperty]
        public Pizza NewPizza { get; set; } = new();

        public void OnGet()
            => pizzas = PizzaService.GetAll();

        public string GlutenFreeText(Pizza pizza)
            => pizza.IsGlutenFree ? "Gluten Free" : "Not Gluten Free";

        public IActionResult OnPost()
        {
            if (!ModelState.IsValid) return Page();
            PizzaService.Add(NewPizza);
            return RedirectToAction("Get");
        }

        public IActionResult OnPostDelete(int id)
        {
            PizzaService.Delete(id);
            return RedirectToAction("Get");
        }
    }
}
