WCF service fails to start when more than one service is available

Question

I am running a WCF service from inside a exe (for debugging, it will be moved to the windows service when deployed) I got one service running fine inside of it however when I run a second service I get the exception

System.InvalidOperationException was unhandled
  Message=The ChannelDispatcher at 'http://backupsvr:8082/' with contract(s) '"IHttpGetHelpPageAndMetadataContract"' is unable to open its IChannelListener.
  Source=System.ServiceModel

            at System.ServiceModel.Dispatcher.ChannelDispatcher.OnOpen(TimeSpan timeout)
       InnerException: 

here is the code that calls it.

using(ServiceHost hostRemoteUserManager = new ServiceHost(typeof(RemoteUserManager)))
using(ServiceHost hostDatabaseManagement = new ServiceHost(typeof(DatabaseManagement)))
try
{
    // Open the ServiceHost to start listening for messages.
    hostRemoteUserManager.Open();
    hostDatabaseManagement.Open(); //Exception on this line.
    // The service can now be accessed.
    Console.WriteLine("The service is ready.");
    Console.WriteLine("Press <ENTER> to terminate service.");
    Console.ReadLine();

    // Close the ServiceHost.
    hostRemoteUserManager.Close();
    hostDatabaseManagement.Close();
}

And here is my App.config file I used the Service Configuration Editor in visual studio 2010 to create it.

REMOVED

What do I need to change in my App.config file to allow more than one service other than running them on different ports. I would like to query http://backupsvr:8082/ and have it list all of the services available when I use the "Add Service Refrence" tool.

UPDATE --

I did Igor's suggestion it now runs on the same port however in the Add service refrence dialog I still need to type in http://backupsvr:8082/RemoteUserManager and http://backupsvr:8082/DatabaseManagement insted of just one http://backupsvr:8082/ . I do not know if what I am wanting is possable, it seems that is the way it should be by the way the dialog is designed. here is a update copy of my app.config file

Answer 1

use for first service

<baseAddresses>
      <add baseAddress="net.tcp://backupsvr:8082/IRemoteUserManager"/>
    </baseAddresses>

use for second service

<baseAddresses>
      <add baseAddress="net.tcp://backupsvr:8082/IDatabaseManagement"/>
    </baseAddresses>

addresses should be unique
