How to make a dropdownlist with data from database in ASP.NET Core MVC

I have figured out how to make a dropdownlist with static data, but I want to display data from my database. How do I fill my list with data from the model Neighbourhoods? I want to display all the NeighbourhoodNames in my dropdown.

I am using .net core 5.0 with MVC

My cshtml code:

    <select asp-for="Neighbourhood" asp-items="Model.NeighbourhoodList"></select>

My Model:

    using Microsoft.AspNetCore.Mvc.Rendering;
    using System;
    using System.Collections.Generic;
    using Microsoft.EntityFrameworkCore;

    namespace MyProject.Models
    {
        [Keyless]
        public partial class Neighbourhoods
        {
            public string NeighbourhoodGroup { get; set; }
            public string NeighbourhoodName { get; set; }
            public List<SelectListItem> NeighbourhoodList { get; } = new List<SelectListItem>
            {
                new SelectListItem { Value = "a", Text = "New York" },
                new SelectListItem { Value = "b", Text = "Los Angeles" },
            };
        }
    }

My Controller:

        // GET: Neighbourhoods/Create
        public IActionResult Create()
        {
            var vm = new Neighbourhoods();
            return View(vm);
        }
