WCF分布式开发常见错误(12)：The server was unable to process the request,服务无法处理请求

    进行WCF编程过程中会遇到这样的错误：服务无法处理的请求由于内部错误。    具体信息如下：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 3.0 SDK documentation and inspect the server trace logs.

错误截图：

    由于内部错误，无法处理请求。

解决办法：

在服务行为里配置错误属性即可：

添加如下代码到服务类：

[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
