Как исправить ошибку 'Html.PagedListPager ()'

Question

Привет, я сейчас работаю над сайтом, который нуждается в подкачке страниц. Тем не менее, я получаю сообщение об ошибке:

Код серьезности Описание Состояние подавления строки файла проекта Ошибка CS1929 «IHtmlHelper>» не содержит определения для «PagedListPager» и наилучшей перегрузки метода расширения «HtmlHelper.PagedListPager (HtmlHelper, IPagedList, Func)» требует приемник типа «HtmlHelper» MVCManukauTech

Я уже добавил использование операторов для PagedList, PagedList.Mvc и X.PagedList.Mvc.Core.

Мой контроллер:

  using System;
  using System.Collections.Generic;

  using System.Linq;
  using System.Threading.Tasks;
  using Microsoft.AspNetCore.Mvc;
  using Microsoft.AspNetCore.Mvc.Rendering;
  using Microsoft.EntityFrameworkCore;
  using MVCManukauTech.Models.DB;
  using MVCManukauTech.ViewModels;
  using PagedList;
  using X.PagedList.Mvc.Core;
  using PagedList.Mvc;


  namespace MVCManukauTech.Controllers
{
public class CatalogController : Controller
{
    private readonly F191_Grace_ProjectContext _context;

    public CatalogController(F191_Grace_ProjectContext context)
    {
        _context = context;
    }




    public IActionResult Index(string searchBy, string search, int? page) 
    {
        //140903 JPC add CategoryName to SELECT list of fields
        string SQL = "SELECT ProductId, Product.CategoryId AS CategoryId, Name, ImageFileName, UnitCost"
            + ", SUBSTRING(Description, 1, 100) + '...' AS Description, CategoryName "
            + "FROM Product INNER JOIN Category ON Product.CategoryId = Category.CategoryId ";
        string categoryName = Request.Query["CategoryName"];

        if (categoryName != null)
        {
            //140903 JPC security check - if ProductId is dodgy then return bad request and log the fact 
            //  of a possible hacker attack.  Excessive length or containing possible control characters
            //  are cause for concern!  TODO move this into a separate reusable code method with more sophistication.
            if (categoryName.Length > 20 || categoryName.IndexOf("'") > -1 || categoryName.IndexOf("#") > -1)
            {
                //TODO Code to log this event and send alert email to admin
                return BadRequest(); // Http status code 400
            }

            //140903 JPC  Passed the above test so extend SQL
            //150807 JPC Security improvement @p0
            SQL += " WHERE CategoryName = @p0";
            //SQL += " WHERE CategoryName = '{0}'";
            //SQL = String.Format(SQL, CategoryName);
            //Send extra info to the view that this is the selected CategoryName
            ViewBag.CategoryName = categoryName;
        }

        //150807 JPC Security improvement implementation of @p0
        var products = _context.CatalogViewModel.FromSql(SQL, categoryName);
        return View(products.ToList().ToPagedList( page??1, 6));



    }

My View:

  @using PagedList.Mvc;
  @using X.PagedList.Mvc.Core;
  @using PagedList;
  @model IPagedList<MVCManukauTech.ViewModels.CatalogViewModel>
  @{

//Are we showing all the products or only one category?
if (ViewBag.CategoryName == null)
{
    ViewBag.Title = "Catalog";
}
else
{
    ViewBag.Title = "Catalog - " + ViewBag.CategoryName;
}
}
<link href="~/css/StyleSheet.css" rel="stylesheet" />

 <div class="bg">
