C# 默认HTTP头IIS 7'；MvcHandler'；在当前上下文中不存在

这是我在Global.asax中的代码

<%@ Application Language="C#" %>

<script runat="server">



    protected void Application_PreSendRequestHeaders()
    {
       Response.Headers.Remove("Server");
       Response.Headers.Remove("X-AspNet-Version");
       Response.Headers.Remove("X-AspNetMvc-Version");

    }


</script>

但是我收到了这个错误： 当前上下文中不存在名称“MvcHandler”

在我的Web配置中，我使用以下代码

<configuration>

    <system.web>
    <httpRuntime enableVersionHeader="false" targetFramework="4.5" />
    <compilation debug="true" targetFramework="4.5"/>
    </system.web>
  <system.webServer>

     <httpProtocol>
      <customHeaders>
      <clear />
        <remove name="X-Powered-By" />
      </customHeaders>
   </httpProtocol>

    <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">

如何删除MVC默认HTTP头？

---

我无法删除HTTP头，我在这一行收到一个错误名称“MvcHandler”在当前上下文中不存在

可能重复@Fran我更新了代码，我在mvc中是如此的新，需要添加框架或？@Fran It's not duplicate这是我的错误名称“MvcHandler”在当前上下文中不存在在System.Web.Mvc中。如果要在asax而不是.cs文件中编写处理程序，则需要在.asax文件中包含System.Web.Mvc。你为什么不为Global.asax准备一个代码？这些是在创建项目时创建的。
