在 IIS Express 中一切正常，但是当我调试到本地 IIS 时，尝试在应用程序中使用 WCF（如下所列）时出现错误，浏览器显示，但 VS 没有。

') occurred in iexplore.exe [856].

The Just-In-Time debugger was launched without necessary security permissions. To debug this process, the Just-In-Time debugger must be run as an Administrator. Would you like to debug this process?

我有解决办法。我的头，它的工作方式很奇怪......

因此，您需要转到控制面板 - 程序和功能 - 打开或关闭功能，并且您必须在此处启用所有WCF 服务树（如果您不及早检查，也请检查 ASP.NET）。
