如何在System.Web.Mvc.MvcHandler上调试500.0 / 0x00000000错误 [英] How to debug 500.0 / 0x00000000 error on System.Web.Mvc.MvcHandler

问题描述

我收到了这个奇怪的错误，我无法弄明白。在Windows 8.1，IIS 8.5上运行。该站点在Microsoft Azure上运行正常，因此它必须是本地配置问题。我在IIS Express中遇到与IIS相同的错误。

I'm getting this strange error which I am unable to figure out. Running on Windows 8.1, IIS 8.5. The site runs fine on Microsoft Azure so it must be a local configuration issue. I get the same errors in IIS Express as I do with IIS.

这个问题已经存在了几天，这让我很精神。我甚至无法测试简单的CSS /内容更改（我正在尝试做的事情），而不是每次都要将它们推送到Azure。

The problem has been around for a few days and it's driving me mental. I can't even test simple CSS/Content changes (which is what I am trying to do) without pushing them up to Azure each time to check.

错误：

Module          global.asax

以下是警告前的部分的追踪。

Here is the trace for the section just before the warning.

我试过的东西

• 重新安装IIS，.NET 4.5，Visual Studio


• 检查权限：IIS_IUSRS可以访问文件夹和文件


• 安装了一个基本的MVC 5演示应用程序。在网站上完美运行&有问题的应用程序池。


• 在我的网站目录的根目录中放置一个基本的aspx hello world页面。它在默认网站上加载，但是在相关网站下我收到PageHandlerFactory-Integrated-4.0错误。

• Reinstall IIS, .NET 4.5, Visual Studio
• Checked permissions: IIS_IUSRS has access to the folder and files
• Installed a basic MVC 5 demo app. Runs perfectly under the website & app-pool in question.
• Put a basic aspx hello world page in the root of my website directory. It loads when in the Default web site, but when under the website in question I get a "PageHandlerFactory-Integrated-4.0" error.

推荐答案

我正在努力处理同样的错误消息，我无法进行任何跟踪或记录。经过几天的研究，我意识到这是Global.asax.cs中一个未处理的例外。我建议您审核Global.asax代码以查看是否有机会发生例外。

I was struggling with this same error message and I couldn't get any tracing or logging to happen. After days of research I realized it was an unhandled exception in Global.asax.cs. I would recommend auditing your Global.asax code to see if there is any opportunity for exceptions to happen.

无论如何，您可能希望遵循最佳实践来处理此类应用程序-level错误将最后一条错误消息输出到自定义页面：

Regardless, you might want to follow the best practice to handle such Application-level errors to output the last error message to a custom page:
