Aps.net MVC Core 2.0.0 And Error InvalidOperationException: The view 'List' was not found

Hi

i Create a Project with .core and asp.net Core 2.0.0  === SportsStore in pdf Pro Asp.net Core MVC Adam Freeman

i Create a Custome TagHelper :

namespace SportsStore.Infrastructure
{
    [HtmlTargetElement("div",Attributes = "page-model")]
    public class PageLinkTagHelper:TagHelper
    {
        private IUrlHelperFactory urlHelperFactory;
        public PageLinkTagHelper(IUrlHelperFactory helperFactory)
        {
            urlHelperFactory = helperFactory;
        }
        [ViewContext]
        [HtmlAttributeNotBound]
        public ViewContext ViewContext { get; set; }
        public PagingInfo PageModel { get; set; }
        public string PageAction { get; set; }
        public override void Process(TagHelperContext context, TagHelperOutput output)
        {
            IUrlHelper urlHelper = urlHelperFactory.GetUrlHelper(ViewContext);
            TagBuilder result = new TagBuilder("div");
            for (int i = 1; i <= PageModel.TotalPages; i++)
            {
                TagBuilder tag = new TagBuilder("a");
                tag.Attributes["href"] = urlHelper.Action(PageAction,
                new { page = i });
                tag.InnerHtml.Append(i.ToString());
                result.InnerHtml.AppendHtml(tag);
            }
            output.Content.AppendHtml(result.InnerHtml);
        }
    }
}

and i Change Route System :

app.UseMvc(routes => {

                routes.MapRoute(
                name: "pagination",
                template: "Products/Page{page}",
                defaults: new { Controller = "Product", action = "List" });

                routes.MapRoute(
                     name: "default",
                     template: "{controller=Product}/{action=List}/{id?}");
            });

next when i Run my Project and clicked on Number From Pagination i Get Error :

An unhandled exception occurred while processing the request.

InvalidOperationException: The view 'List' was not found. The following locations were searched:
/Views/Shared/List.cshtml

code in Controller :

public class ProductController : Controller
    {
        private IProductRepository repository;
        public int PageSize = 4;

        public ProductController(IProductRepository repo)
        {
            repository = repo;
        }
        // GET: /<controller>/
        public ViewResult List(int page = 1)


            => View(new ProductsListViewModel {Products= repository.Products
             .OrderBy(p => p.ProductID)
             .Skip((page - 1) * PageSize)
             .Take(PageSize),

                PagingInfo=new PagingInfo { CurrentPage=page,ItemsPerPage=PageSize,TotalItems=repository.Products.Count() }
            });


    }

code in List.cshtml :

@model ProductsListViewModel

@foreach (var p in Model.Products)
{
        <div><h3>@p.Name</h3>
            @p.Description<h4>@p.Price.ToString("c")</h4></div>
}<div page-model="@Model.PagingInfo" page-action="List"></div>
