wpf FaultException 未处理

FaultException was unhandled

提问by sipkowich

I am running a WCF service and a WPF application. as soon as I call data on the wpf application this error displays.

我正在运行 WCF 服务和 WPF 应用程序。只要我在 wpf 应用程序上调用数据，就会显示此错误。

Error:

错误：

An unhandled exception of type 'System.ServiceModel.FaultException' occurred in mscorlib.dll

Additional information: The server was unable to process the request due to an internal error.  For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs.

I think the problem is from my service but not so sure, any suggestions?

我认为问题出在我的服务上，但不太确定，有什么建议吗？

As the error message suggests, change the includeExceptionDetailsInFaults to true in the serviceDebug configuration (web.config):

如错误消息所示，将 serviceDebug 配置 (web.config) 中的 includeExceptionDetailsInFaults 更改为 true：

<serviceDebug includeExceptionDetailInFaults="true"/>

so you will get the exception from the service.

所以你会从服务中得到异常。
