推荐答案

includeExceptionDetailsInFaults = true

服务器端配置中的serviceDebug属性。



我相信该服务至少会受到客户端的攻击。但是，要调试此方案，请尝试通过浏览器加载您的服务并手动点击该方法。如果它返回正常，则问题出在客户端配置中。通过包含此属性，您可以更清楚地了解正在发生的事情。



同时更新您的服务引用，以确保您拥有wsdl的最新副本，以防您在创建服务引用后更新服务。 />


获得实际的堆栈跟踪后，确定它显示应用程序的点（忽略框架线）并发布那些。

for the serviceDebug attribute in server side configuration.

I believe that the service atleast gets hit by the client. However, to debug this scenario, try to load your service through browser and manually hit the method. If it returns fine, then the issue is in client side configuration. By including this attribute, you can be more clear about what's happening.

Also update your service reference once so that you are sure that you have a latest copy of wsdl just in case you updated the service after creating the service reference.

Once you get the actual stack trace, identify the points where it shows about the application (ignore the framework lines) and the post those.
