通过 IIS 配置的 Web 应用程序-ASP.net 4.6
此应用程序从 SQL 数据库（报告服务器）读取/解析数据。基本上，它根据前端用户使用相关桌面软件获取的 SQL 数据生成报告
我可以到达登录页面并进入主页，但单击网站上的任何链接都会产生以下错误：

我尝试了所有可能的方法来解决这个问题，从修改 SSL、应用程序设置，到验证与应用程序池关联的域帐户的权限。还尝试了 IIS 重置。
我用谷歌搜索了这些错误，发现了类似的情况 - 但是，提供的解决方案似乎涉及修改源代码，而我对此不太熟悉。例如https://github.com/dotnet/corefx/issues/25800
我找到了另一个解决方案，表明 OWIN 管道是罪魁祸首，并建议添加：
#if !DEBUG
app.Use(async (ctx, next) =>
{
try
{
await next();
}
catch (OperationCanceledException)
{
}
});
#endif

这是我的问题：我不知道在哪里添加这样的代码。我知道如何使用 Visual Studio 打开与 DLL 关联的 xml 文件，但当我搜索程序的目录时，我看到了大量 Microsoft“owin”xml 文件。
我不知道该编辑哪一个来尝试上述解决方案。我尝试Microsoft.Owin.xml使用该代码进行修改（将其添加到开头，在 assemly 标签之后）。
我需要一些指导，关于我应该在哪个特定文件中添加这样的代码行，而且我不确定上述解决方案是否正确（尽管可能是）
