The process does not have access rights to this namespace

I am making a personalized WCF encoder following the guidelines of this site using-mtom

I create a web Service by taking a file.zip

    public class Service1 : IService1
{
    public FileResponse GetData(string value)
    {
        FileResponse response = new FileResponse
        {
            Filename = "Archivo de Prueba",
            Contents = File.ReadAllBytes(@"C:\temp2A25FEEFBA.zip")
        };

        return response;
    }
}

class projects are like this:

In the console (CnsTestService) I have the following lines:

    class Program
{
    static void Main(string[] args)
    {

        string baseAddress = "http://localhost:62859/Service1.svc";
        ServiceHost host = new ServiceHost(typeof(Service1), new Uri(baseAddress));
        host.Description.Behaviors.Add(new ServiceMetadataBehavior { HttpGetEnabled = true });
        host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexHttpBinding(), "mex");
        CustomBinding binding = new CustomBinding(
            new TextOrMtomEncodingBindingElement(),
            new HttpTransportBindingElement());
        CustomBinding mtomBinding = new CustomBinding(new MtomMessageEncodingBindingElement(), new HttpTransportBindingElement());
        host.AddServiceEndpoint(typeof(IService1), binding, "").Behaviors.Add(new IncomingEncoderInspector());
        host.AddServiceEndpoint(typeof(IService1), mtomBinding, "mtom");
        host.Open();
        Console.WriteLine("Host opened");

        for (int i = 0; i < 3; i++)
        {
            MessageEncodingBindingElement mebe;
            string address;
            switch (i)
            {
                case 0:
                    mebe = new MtomMessageEncodingBindingElement();
                    address = baseAddress + "/mtom";
                    Console.WriteLine("Using MTOM to MTOM-only endpoint");
                    break;
                case 1:
                    mebe = new MtomMessageEncodingBindingElement();
                    address = baseAddress;
                    Console.WriteLine("Using MTOM to TextAndMtom endpoint");
                    break;
                default:
                    mebe = new TextMessageEncodingBindingElement();
                    address = baseAddress;
                    Console.WriteLine("Using TEXT to TextAndMtom endpoint");
                    break;
            }

            CustomBinding clientBinding = new CustomBinding(mebe, new HttpTransportBindingElement());
            ChannelFactory<IService1> factory = new ChannelFactory<IService1>(clientBinding, new EndpointAddress(address));
            IService1 proxy = factory.CreateChannel();
            try
            {
                Console.WriteLine(proxy.GetData("foo.bar"));
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
            }

            ((IClientChannel)proxy).Close();
            factory.Close();
        }

        Console.WriteLine("Press ENTER to close");
        Console.ReadLine();
        host.Close();
    }
}

in the Service1.svc code is this way.

the error or warning in the console is in the line host.Open ();

Message = HTTP could not register the URL link .  The process does not have access rights to this namespace (See link for more information).   //~/App_Code/Service.cs C: \ Users \ emiliog \ source \ repos \ TextAndMtom \ ServiceTest \ Service1.cs

WHAT can be the Problem ??
