System.InvalidOperationException:堆栈为空

问题描述

运行Visual Studio 2013中内置的ASP.NET 4.x应用程序后，出现以下异常.

Once running ASP.NET 4.x application built in Visual Studio 2013 I am getting the below exception.

我试图通过删除页面检查器程序集来禁用PageInspector

I have tried to disable the PageInspector by removing page inspector assembly

<assemblies>
    <remove assembly="Microsoft.VisualStudio.Web.PageInspector.Loader, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
</assemblies>

并将此配置添加到应用设置

and adding this configuration to app settings

<appSettings>
    <add key="PageInspector:ServerCodeMappingSupport" value="Disabled"/>
</appSettings>

没有任何帮助.

有什么办法可以避免该异常吗?非常感谢您的任何建议

Is there any way how to avoid the exception?Thanks a lot for any suggestions

推荐答案

System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. -
System.InvalidOperationException: Stack empty.
Microsoft.VisualStudio.Web.PageInspector.Runtime.WebForms.SelectionMappingRenderTraceListener.EndRendering(TextWriter writer, Object renderedObject)
...

按照建议添加后:

 <appSettings>
   <add key="PageInspector:ServerCodeMappingSupport" value="Disabled"/>
   ...
 </appSettings>

我注意到我在下拉列表中有重复的所选项目，从而造成了问题.

I noticed I had duplicate selected item on a dropdown list creating the issue.
