c# - 我在 IIS 中的站点中遇到错误，未找到 Microsoft.EnterpriseManagement.OperationsManager.Apm.DataCollecting.Producers.Mvc.4.0

Question

我已经开始在 IIS 中运行的两个(完全不同的)项目中遇到此错误:

Server Error in '/' Application.
Could not load file or assembly 'Microsoft.EnterpriseManagement.OperationsManager.Apm.DataCollecting.Producers.Mvc.4.0, Version=7.0.5000.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'Microsoft.EnterpriseManagement.OperationsManager.Apm.DataCollecting.Producers.Mvc.4.0, Version=7.0.5000.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' could not be loaded.


WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.6.79.0 

如果我稍等片刻然后刷新页面几次，错误就会消失。我正在运行带有 Visual Studio 2015 的 Windows 10。正如我所说，这些项目完全不同，彼此之间没有任何关系。

Answer 1

真是一团糟。当我回到 4-5 个月前从事的项目时，同样的事情发生在我身上。

关于 application insights 的提示是我找到解决方案的原因，但卸载旧的 application insights 似乎并没有解决问题。

我通过在 Application Insights Status Monitor Preview 中安装解决了这个问题(我通过单击右侧的“从画廊安装应用程序”在 IIS 的 Web 平台安装程序中找到了它)。然后我运行它，我的 IIS 应用程序出现了。我点击了“配置”或任何使它的状态为“已启用”的东西。然后在 Application Instaights Status Monitor Preview 窗口的顶部，我看到一个东西说我正在运行 Microsoft Monitor Agent 或类似的东西，所以我点击那里的按钮，它告诉我重置 IIS。重置 IIS 后它起作用了。
