asp.net mvc调试器抛出SEHException

External component has thrown an exception.

这是堆栈跟踪：

描述：执行当前Web请求期间发生未处理的异常.请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息.

例外细节：

System.Runtime.InteropServices.SEHException: External component has thrown an exception.`

来源错误：

在执行当前Web请求期间生成了未处理的异常.可以使用下面的异常堆栈跟踪来识别有关异常的起源和位置的信息.

堆栈跟踪：

从这里我只能弄清楚调试器在执行此操作时崩溃了

Microsoft.Win32.Win32Native.SafeCreateFile()

这有什么想法吗？
