visual-studio-2010 - “DefaultAppPool”与万维网发布服务发生致命通信错误

Question

我每次访问网站时都会收到事件日志条目:

Event Type: ErrorEvent Source:   VsJITDebuggerEvent Category: NoneEvent ID:   4096User:       NT AUTHORITY\NETWORK SERVICEComputer:   COMPUTER-02Description:An unhandled Microsoft .NET Framework exception occurred in w3wp.exe [2908].

我也听从了Microsoft's Support site的建议没有运气。网络服务帐户在访问注册表时没有任何问题。

我需要在 IIS6(而不是 IIS Express 7.5)中运行该站点，因为该站点运行 ASP 和 ASP.NET 我需要通配符映射以在 ASP 中进行身份验证。

我已经完全没有想法了，因为该网站在 ASP.NET 3.5(CLR v2 ...)中很好，但是这次升级因调试而完全搞砸了。

任何帮助将不胜感激。

您将需要 WinDbg(Windows 调试工具)和 DebugDiag。

1. 安装 DebugDiag 和 WinDbg
2. 确保您已将相关框架的 SOS.dll 复制到 WinDbg 目录。
3. 添加规则以捕获 IIS/COM+ 进程
4. 在第一次出现异常时，创建一个完整的用户转储。限制为 10
5. 打开网站并查看 DebugDiag，您应该会发现它开始进行完全转储。
6. 获得一些内存转储后，加载 WinDbg 并单击"file"->“打开故障转储”并加载其中一个内存转储。
7. 输入.load sos
8. 键入 !clrstack
9. 您将获得错误的堆栈跟踪信息，例如:

无论如何，对我来说，您可以看到 Debugger.Launch() 就在顶部，低看，我的代码包含它。似乎 IIS 不喜欢那样如果这是您的第一行代码，则完全没有!
