我使用 Visual Studio 2012 for Web Express 在 ASP.Net 4.5 中开发了一个 Web 表单。它托管在 somee.com 上。当页面加载时，我收到以下错误：

Server Error in '/' Application.

您需要确保您拥有对与“webopt”文件相关的特定程序集的引用。通常，您可以通过将其包含在 web.config 文件的部分中来执行此操作：

<pages>
    <controls>
        <add tagPrefix="webopt" assembly="Microsoft.AspNet.Web.Optimization.WebForms" namespace="Microsoft.AspNet.Web.Optimization.WebForms"  />
    </controls>
</pages>

实际上比这更简单。只需在 Nuget 上运行：Install-Package Microsoft.AspNet.Web.Optimization.WebForms

false只需将 debug 属性设置为in即可打开捆绑和缩小web.config。

右键单击您的 Web.config 并检查“构建操作”属性。如果设置为“无”，您将看到“未知服务器标签 'webopt:bundlereference”错误。将其更改为“内容”，一切都会好起来的。
