I am hosting WCF service but I am facing error.

WCFServices

error message:
A binding instance has already been associated to listen URI 'http://localhost:8080/RemService'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config.

CODE :

using (System.ServiceModel.ServiceHost host = new System.ServiceModel.ServiceHost(typeof(REMService.REMServices)))
            {
                host.Open();
                Console.WriteLine("Service Started at" + DateTime.Now);
                Console.ReadLine();
            }

What I have tried:

<configuration>
  <system.servicemodel>
    <services>
      <service name="REMService.REMServices" behaviorConfiguration="mexBehavior">
        <endpoint name="basic" address="RemService" binding="basicHttpBinding" contract="REMService.IREMServices">
        <endpoint address="RemService" binding="netHttpBinding" contract="REMService.IREMServices">
        <endpoint name="mex" address="mex" binding="mexHttpBinding" contract="IMetadataExchange">
        <host>
          <baseaddresses>
