使用 Razor Pages 在 Asp.NET Core 2.2 中找不到 ViewComponent

ViewComponent not found in Asp.NET Core 2.2 using Razor Pages

我创建了一个非常简单的视图组件(/ViewComponents/MenuViewComponent.cs):

namespace MySite.ViewComponents
{    
    public class MenuViewComponent : ViewComponent
    {
        public Task<IViewComponentResult> InvokeAsync()
        {
            return Task.FromResult((IViewComponentResult)View("Default"));
        }
    }
}

查看部分在这里(/Pages/Components/Menu/Default.cshtml):

<div>Menu</div>

我正在从 _Layout.cshtml 文件中调用 菜单 ,如下所示:

@await Component.InvokeAsync("MenuViewComponent");

查看页面时出现以下错误消息:

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'.

问题:
我缺少什么才能使它正常工作?

确保组件视图位于如下所述的搜索路径中

引用View components in ASP.NET Core

并且在调用组件时只需使用不带后缀的名称

@await Component.InvokeAsync("Menu")
