c# - 无法加载文件或程序集 'Microsoft.AspNet.TelemetryCorrelation' 或其依赖项之一。该系统找不到指定的文件

Question

我在 IIS 7(本地 Windows 10 专业版)下有两个 Web 应用程序。根是 MVC .Net 版本 4.7.1。到目前为止，这里的一切似乎都运行良好。但是，在默认站点根目录下设置为单独的应用程序是较旧的 .Net 4.0 版 WebForms 应用程序。

第 4 版应用程序是在 Visual Studio 2015 中构建的，MVC 是使用 Visual Studio 2017 构建的。我让第 4 版 WebForms 应用程序在具有相同设置的不同网站下运行，并且运行良好。它只有在作为不同应用程序在根节点下运行时才会出现问题。我还尝试在两个应用程序上使用不同的应用程序池，以及使用相同的应用程序池，但错误没有发生变化。

我也尝试过卸载 ApplicationInsights 并禁用它，但我遇到了同样的问题。

Answer 1

在我的例子中，子应用没有使用 ApplicationInsights，我将这些排除项添加到子应用 web.config 文件中。它解决了问题。

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="false">
      <remove name="TelemetryCorrelationHttpModule" />
      <remove name="ApplicationInsightsWebTracking" />
    </modules> 
  </system.webServer>
</configuration>
