Getting Connection Refused with WCF Service

Getting Connection Refused with WCF Service

I made an service using WCF and can't connect to it, I keep getting the
following error:
Could not connect to net.tcp://localhost:5555/ControlChannel. The
connection attempt lasted for a time span of 00:00:02.0139182. TCP error
code 10061: No connection could be made because the target machine
actively refused it 127.0.0.1:5555.
This is the code:
Contract:
[ServiceContract(CallbackContract = typeof(IControlChannelCallback))]
public interface IControlChannel
{
[OperationContract]
void Join();
}
CallBackContract:
public interface IControlChannelCallback
{
[OperationContract(IsOneWay = true)]
void ShowMessage(string message);
}
Service:
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single,
IncludeExceptionDetailInFaults = true)]
public sealed class ControlChannel : IControlChannel
{
public static readonly IList<IControlChannelCallback> Callbacks = new
List<IControlChannelCallback>();
public void Join()
{
var client =
OperationContext.Current.GetCallbackChannel<IControlChannelCallback>();
if (!Callbacks.Contains(client))
Callbacks.Add(client);
client.ShowMessage("This message came from the server");
}
}
Server:
public MainForm()
{
InitializeComponent();
using (var host = new ServiceHost(typeof(ControlChannel)))
{
host.Open();
}
}
Client:
public MainForm()
{
InitializeComponent();
var callback = new ControlChannelCallbackClient();
using (var factory = new
DuplexChannelFactory<IControlChannel>(callback, "Client"))
{
var proxy = factory.CreateChannel();
proxy.Join();
}
}
App.config client:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.serviceModel>
<client>
<endpoint name="Client"
contract="Service.Contracts.Interfaces.IControlChannel"
binding="netTcpBinding"
address="net.tcp://localhost:5555/ControlChannel" />
</client>
</system.serviceModel>
</configuration>
App.config server
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.serviceModel>
<services>
<service name="Service.Contracts.Objects.ControlChannel">
<endpoint contract="Service.Contracts.Interfaces.IControlChannel"
binding="netTcpBinding"
address="net.tcp://localhost:5555/ControlChannel" >
</endpoint>
</service>
</services>
</system.serviceModel>
</configuration>
What am I doing wrong? Is it a code problem or should I start looking for
problems elsewhere?
