Question

我有一个WPF应用程序，正在使用WCF终结点但是，当我尝试调用该服务时，出现以下错误，有趣的是，有时它正在工作，但是大多数情况下，我收到以下错误

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

Additional information: The content type text/html of the response message 
does not match the content type of the binding (text/xml; charset=utf-8). If 
using a custom encoder, be sure that the IsContentTypeSupported method is 
implemented properly. The first 75 bytes of the response were: 'The page 
cannot be displayed because an internal server error has occurred.'.
