If you have migrated a project from Visual Studio 2005 to Visual Studio 2008 there is no option to create the global.asax file. Right click solution explorer -> Add New Item  and "Global Application Class" is not there. Here is the skeleton global.asax file if anyone needs it:

 

<%@ 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>
