asp.net-mvc - 找不到类型或命名空间名称“IndexModel”（您是否缺少 using 指令或程序集引用？）

Question

在编译基于 ABP Commercial 的解决方案后，我遇到了以下几个错误。

Severity    Code    Description Project File    Line    Suppression State
Error   CS0246  The type or namespace name 'IndexModel' could not be found (are you missing a using directive or an assembly reference?)    ClientsLink.IdentityServer  D:\Century\Internal\MyProduct\MyProduct\aspnet-core\src\MyProduct.IdentityServer\obj\Debug\net5.0\Razor\Pages\Index.cshtml.g.cs 215 Active

我无法判断这是 Visual Studio 2022 应用程序、Roslyn 编译器中的错误，还是与 Razor 相关的错误，但它是间歇性的。我认为要指出的关键是该Index.cshtml.g.cs文件不在我的解决方案中。这是我构建时创建的某种自动生成的临时文件（注意路径）。

以下是该文件的内容：

这是index.cshtml生成该文件的文件：

@page

@using Volo.Abp.Users
@model IndexModel

            </div>
        </abp-column>
    </abp-row>
</div>

这是相关的index.cshtml.cs文件：

using Microsoft.AspNetCore.Mvc;
using Volo.Abp.AspNetCore.Mvc.UI.RazorPages;

namespace MyProduct.Pages
{
    public class IndexModel : AbpPageModel
    {
        public ActionResult OnGet()
        {
            if (!CurrentUser.IsAuthenticated)
            {
                return Redirect("~/Account/Login");
            }

            return Page();
        }
    }
}

另一个奇怪的是，每次我双击错误打开Index.cshtml.g.cs文件时，Visual Studio 都会锁定，我必须杀死进程并重新启动它。

如果您熟悉 MVC 或 ABP 框架，您应该知道我的每个 cshtml 文件都会出现同样的问题。

如何解决这些错误？谢谢。
