This article mainly introduces how to do WCF mistakes, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

1. An error is reported after running self-hosting:

System.ServiceModel.AddressAccessDeniedException' occurred in System.Servic

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

Run cmd with administrator privileges to solve the problem of HTTP namespace protection. After you open cmd, run

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

two。

System.ServiceModel.CommunicationObjectFaultedException

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

And check the timeout displayed in stack, guess that the permissions are not enough, restart vs, and right-click to select Properties-> compatibility-> run as an administrator.

Success

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.

Problem: WCF security issues, if you do not need to consider security, the easiest way to set security.mode to Node.

For example, add code to service:

WSHttpBinding wsb = new WSHttpBinding ()

Wsb.Name = "TestBinding"

Wsb.Security.Mode = SecurityMode.None

Add code to client:

WSHttpBinding wsb = new WSHttpBinding ()

Wsb.Name = "TestBinding"

Wsb.Security.Mode = SecurityMode.None

Wsb.Security.Message.ClientCredentialType = MessageCredentialType.None

4. If the WCF server is remote, you need to enter the start number on the server and add a rule in the firewall.
