由于我将主机更改为ASP.NET 4.0 Web窗体和IIS7集成模式,我的网站通常会出现以下错误：
[NullReferenceException: Object reference not set to an instance of an
object.] System.Web.PipelineStepManager.ResumeSteps(Exception
error) +197
System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext
context,AsyncCallback cb) +89
System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest
wr,HttpContext context) +189
但是,网站工作正常.如何解决这个问题？
