C# AdWords可以在一个磁盘上工作，但不能在另一个磁盘上工作？

背景：Azure；C#；Visual Studio社区2015；Google.Ads.Common.3.14.0；Google.AdWords.18.26.1

最奇怪的事。我在C#中构建了一个命令行应用程序，列出我们管理的账户的所有预算。解决方案文件位于E:\Sources\BudgetLister（E:是Azure驱动器）中。我想从Azure C:驱动器（C:\Web\ARC）运行它

它完全可以从项目的bin/Debug文件夹运行。当我将EXE和相关DLL复制到C:并启动EXE时，一切都会正常运行，直到遇到第一个特定于AdWords的指令。然后我得到

Unhandled Exception: System.ApplicationException: The SoapListenerExtension class is not loaded. The most possible cause for this error is that you haven't registered Google.Api.Ads.Common.Lib.SoapListenerExtension as a soap extension under configuration/system.web/webServices/soapExtensionTypes in your your App.config or Web.config. See the sample App.config for details on how to register soap extensions.

现在我确定我已经

在App.config中的configuration/system.web/webServices/soapExtensionTypes下注册了Google.Api.Ads.Common.Lib.SoapListenerExtension作为soap扩展名，因为我可以在IDE的App.config文件中看到它。此外，如果我没有从E:drive启动，它也不会工作。那么为什么它对C:不起作用呢
