The type of namespace name '_comicBookRepository' could not be found

I'm a bit confused, I am working in Visual Studio along side this course and have the following error message when building, I feel a little lost in this video at this point so am struggling to find the issue myself...

ComicBooksController.cs

using DemoProject.Data;
using DemoProject.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace DemoProject.Controllers
{
    public class ComicBooksController : Controller
    {
        private ComicBookRepository _comicBookRepository = null;

        public ComicBooksController()
        {
            _comicBookRepository = new ComicBookRepository();
        }

        public ActionResult Detail(int? id)
        {
            if (id == null)
            {
                return HttpNotFound();
            }

            var comicBook = new _comicBookRepository.GetComicBook(id.Value);

            return View(comicBook);
        }
    }
}

ComicBookRepository.cs

using DemoProject.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DemoProject.Data
{
    public class ComicBookRepository
    {
        private static ComicBook[] _comicBooks = new ComicBook[]
        {

                Artists = new Artist[]

                },
                Favorite = false
            }
        };

        public ComicBook GetComicBook(int id)
        {
            ComicBook comicBookToReturn = null;

            foreach (var comicBook in _comicBooks)
            {
                if (comicBook.Id == id)
                {
                    comicBookToReturn = comicBook;

                    break;
                }
            }
            return comicBookToReturn;
        }
    }
}

Any help you can give me would be amazing! :D
