我創建了一個非常簡單的視圖組件（/ViewComponents/MenuViewComponent.cs）：namespace MySite.ViewComponents{        public class MenuViewComponent : ViewComponent    {        public Task<IViewComponentResult> InvokeAsync()        {            return Task.FromResult((IViewComponentResult)View("Default"));        }    }}視圖部分在這里（/Pages/Components/Menu/Default.cshtml）：<div>Menu</div>我從文件中調用菜單，_Layout.cshtml如下所示：@await Component.InvokeAsync("MenuViewComponent");查看頁面時，我收到以下錯誤消息：InvalidOperationException: A view component named 'MenuViewComponent' could not be found.A view component must be a public non-abstract class, not contain any generic parameters, and either be decorated with 'ViewComponentAttribute' or have a class name ending with the 'ViewComponent' suffix. A view component must not be decorated with 'NonViewComponentAttribute'.問題：為了讓它正常工作，我缺少什么？
