asp.net – 为什么VS 2008 SP1不允许我编辑global.asax？

我在应用程序中添加了一个global.asax文件,但由于一些奇怪的原因,Visual Studio 2008 SP1不允许我编辑脚本标记之间的任何代码,即将代码添加到事件处理程序,如Application_Start,Session_Start.但是VS让我在脚本标签之外进行编辑.

这只是一个使用内置Web服务器的基于文件的简单Web应用程序.

有什么想法发生了什么？

这是代码内联global.asax VS创建：

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

<script runat="server">
    void Application_Start(object sender,EventArgs e) 
    {
        // Code that runs on application startup
    }

    void Application_End(object sender,EventArgs e) 
    {
        //  Code that runs on application shutdown
    }

    void Application_Error(object sender,EventArgs e) 
    { 
        // Code that runs when an unhandled error occurs
    }

    void Session_Start(object sender,EventArgs e) 
    {
        // Code that runs when a new session is started
    }

    void Session_End(object sender,EventArgs e) 
    {
        // Code that runs when a session ends. 
        // Note: The Session_End event is raised only when 
        // the sessionstate mode
        // is set to InProc in the Web.config file. 
        // If session mode is set to StateServer 
        // or SQLServer,the event is not raised.
    }
</script>
