当前Web请求执行期间发生未处理的异常

Question

突然，当我运行我的Web应用程序时，出现此错误：

无法加载文件或程序集'file：/// C：\\ Users \\ rafael \\ AppData \\ Local \\ Temp \\ Temporary ASP.NET Files \\ root \\ 284bddf3 \\ 431c8965 \\ App_Web_homepage.aspx.cdcab7d2.vmizb1js.dll'或以下之一它的依赖性。 句柄无效。 （来自HRESULT的异常：0x80070006（E_HANDLE））

这是堆栈跟踪：

我不知道这是怎么回事。 因此，如果能得到任何帮助，我将不胜感激。

Answer 1

您可以选择stop and restart the website吗？

从理论上讲，这应该recycle the application pool for your site ，这可能足以纠正问题。

希望对您有帮助。

Answer 2

在服务器上执行以下操作：

1. 打开命令提示符并运行以下命令：
2. C：\\ WINDOWS \\ Microsoft.NET.NET Framework \\ Framework版本\\ aspnet_regiis.exe -i

可以用应用程序项目的.NET框架替换.NET框架版本的地方。 v2.0.50727或4.0等

再次尝试运行该应用程序，一切都会好起来的。
