WCF 出錯的解決方法

1. 運行self-hosting以後報錯：

                System.ServiceModel.AddressAccessDeniedException' occurred in System.Servic 

                System.ServiceModel.AddressAccessDeniedException: ... http://+:9999/calculatorService/...

以管理員權限運行cmd，解決HTTP名字空間保護的問題。打開了cmd以後，運行

"netsh http add urlacl http://+:9999/calculatorService/ user=everyone"

2. 

    System.ServiceModel.CommunicationObjectFaultedException

    The communication object, System.ServiceModel.ServiceHost, cannot be used for communication 

而且查看stack 中顯示 timeout，猜測估計是權限不夠，重啓vs，右擊選擇屬性->兼容性->以管理員身份運行。 

成功

3.

'System.ServiceModel.Security.SecurityNegotiationException' occurred in mscorlib.dll

Additional information: SOAP security negotiation with 'http://xlt1159-cn1:9999/messageService' for target 'http://xlt1159-cn1:9999/messageService' failed. See inner exception for more details.

問題：WCF的安全問題，若是不須要考慮安全性，最簡單的方法將security.mode 設置爲Node。

        如在service中添加代碼：

                WSHttpBinding wsb = new WSHttpBinding();

                wsb.Name = "TestBinding";

                wsb.Security.Mode = SecurityMode.None;

        在 client中添加代碼：   

                WSHttpBinding wsb = new WSHttpBinding();    

                wsb.Name = "TestBinding";

                wsb.Security.Mode = SecurityMode.None;

                wsb.Security.Message.ClientCredentialType = MessageCredentialType.None;

4.     WCF服務端若是是remote的，須要在服務端要打開端口號，在防火牆中新增規則。
