Hi!

I have two classes; Item and ItemType.
Item contains ItemTypeId and ItemType contains a list over Items.

But the Items list never gets populated. Its always 0.

Item:

public class Item
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Graphic { get; set; }
    public decimal Price { get; set; }
    public string Description { get; set; }
    public int ItemTypeId { get; set; }
    public virtual ItemType ItemType { get; set; }
}

ItemType:

public class ItemType
{
    public int Id { get; set; }
    public string Name { get; set; }

    public virtual ICollection<Item> Items { get; set; } = new HashSet<Item>();

    public enum ListTypes
    {
        Student = 1,
        Work = 2,
        Gamer = 3,
        Other = 4
    }
}

and this is the View Component that selects ItemType:

public class ItemListViewComponent : ViewComponent
    {
        private Data.TechDbContext _context;

        public ItemListViewComponent(Data.TechDbContext context)
        {
            _context = context;
        }

        public async Task<IViewComponentResult> InvokeAsync(Models.ItemType.ListTypes type)
        {
            var single = await (from t in _context.ItemTypes where t.Id == (int)type select t).FirstAsync<Models.ItemType>();

            return View(single);
        }
    }

It finds the correct ItemType, but the Items property are always 0. (yes I've checeked theres data in the db)

Any help with this will be highly appreciated! (since its driving me crazy)

What I have tried:

I've tried debugging and different methods of selecting data. Drop the database and repopulated the data.
