我正在使用 Visual Studio 2017 在 NET Core 2.1.1 中運行一個項目，但遇到以下問題：視圖未生成相應的 HTML。我有以下控制器：public class CountryController : Controller {    IUnitOfWork Context;    IRepository<Country> countryRepository;    public CountryController(IUnitOfWork context) {        countryRepository = context.GetRepository<Country>();        Context = context;    }    public IActionResult Index() {        CountryViewModel countries = new CountryViewModel(countryRepository.Elements());        return View(countries);    }    public IActionResult Insert (CountryBindingModel country) {        Country Country = new Country();        Country.Name = "Canada";        countryRepository.Insert(Country);        Context.Save();        return RedirectToAction("Index");    }}我有相關的觀點：@using Domain.Models@model CountryViewModel<form asp-controller="Country" asp-action="Insert">    <label asp-for="Name"></label>    <input class="form-control" asp-for="Name"/>    <button type="submit">Add Country</button></form><ul>    @foreach (var a in Model.Countries) {        <li>@(a.Name)</li>;    }</ul>它生成的 HTML 如下，取自瀏覽器，添加國家/地區不起作用：<form asp-controller="Country" asp-action="Insert">    <label asp-for="Name"></label>    <input class="form-control" asp-for="Name"/>    <button type="submit">Add Country</button></form><ul></ul>
