WCF调用异常

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.调用wcf提示错误信息，网上搜索各种解决办法，最后发现是因为单独更新了某个文件应该是程序内部异常了。解决办法是把程序一起更新就可以了。
