IP端点0.0.0.0:9000上通信对象和侦听器的WCF异常

Question

I am getting WCFexception on two things as mentioned below

The communication object, System.ServiceModel.ServiceHost, cannot be used for communication because it is in the Faulted state.

There is already a listener on IP endpoint 0.0.0.0:9000. Make sure that you are not trying to use this endpoint multiple times in your application and that there are no other applications listening on this endpoint.

If we try to browse we get the page cannot be displayed message.If we reboot the server/service it will start working. I am novice to WCF . Please help me in solving the issue.

Thanks in advance.

Please find below the stack trace

I am assuming you are getting this error in visual studio .Go to Properties of your project file. Find Project URL in Web tab. You will find the url like http://localhost:9000/ . Give a different port number here to something like http://localhost:11483/
