ASP.NET Grocer.ly project help

https://www.codecademy.com/paths/build-web-apps-with-asp-net/tracks/asp-net-i/modules/asp-net-page-models/projects/aspnet-grocery-store
Hello,
I am currently on the Grocer.ly ASP.NET project and am having an issue with step 2:

We’ll need to access each grocery item in the page model for the home page.

In Pages/Index.cshtml.cs , define a Foods field that stores the result of Inventory.ToList() .

( Inventory is a static class, and can be accessed by the IndexModel directly.)
The issue I am running into it doesn’t really give enough information on what data type I am supposed to make the food field, in the hint it has the following:

Remember that Inventory.ToList() has a return type of List<GroceryItem> .
If I try public List Foods {get;set;}

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;
using Microsoft.Extensions.Logging;

using GroceryStore.Models;

namespace GroceryStore.Pages
{
  public class IndexModel : PageModel
  {

    [BindProperty]
    public int Rating { get; set; }
    [BindProperty]
    public string Feedback { get; set; }
    [BindProperty]
    public List<GroceryItem> Foods {get;set;}
    public void OnGet()
    {

    }

  }
}

I get the following error which can be seen at the img link

any help would be appreciated.
