在C＃项目中执行当前Web请求期间发生了未处理的异常

Question

运行项目时出现上述错误，堆栈为：

[ThreadAbortException: Thread was being aborted.]
System.Runtime.InteropServices.GCHandle.InternalFree(IntPtr handle) +0
   System.Runtime.InteropServices.GCHandle.Free() +77
   System.Web.Util.GCUtil.UnrootObject(IntPtr pointer) +70
   System.Web.ApplicationStepManager.ResumeSteps(Exception error) +594
   System.Web.HttpApplication.System.Web.IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, Object extraData) +247
   System.Web.HttpRuntime.ProcessRequestInternal(HttpWorkerRequest wr) +643

知道这可能是什么？
