我目前正在一个 MVC3 站点上工作，在 IIS Express 和 VS2010 本地。该应用程序运行良好，直到 IIS Express 挂起，我不得不终止该进程。
从那时起，当我使用 IIS Express 在 VS2010 中运行该站点时，我得到了这个 YSoD：

堆栈跟踪似乎没有指向代码问题。IIS Express 完全有可能是一个红鲱鱼，我实际上在某个地方搞砸了我的代码......但我希望堆栈跟踪/调试器能够捕捉到这一点。
有谁知道我该如何追踪这个？
提前致谢 ：）

我刚刚在VS开发服务器上试了一下，报同样的错误，估计不是IIS Express吧！

项目版本（在 AssemblyInfo.cs 中）如下所示：
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
// General Information about an assembly is controlled through the following
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyTitle("One_Page_Booking_Engine")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("One_Page_Booking_Engine")]
[assembly: AssemblyCopyright("Copyright © 2012")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]
// Setting ComVisible to false makes the types in this assembly not visible
// to COM components. If you need to access a type in this assembly from
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]
// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("287108fb-4a0c-419f-8b35-a3bc0e2f8617")]

我现在尝试删除 and 的内容bin，obj重新启动 VS 并重新启动我的 PC。什么都没有：（我也尝试将站点发布到带有 IIS 的服务器并运行它：我得到完全相同的 YSoD！
