Default RegisterChannel on the client (.NET Remoting)

Hi. I'm working through the .NET Remoting chapter of the book, and I have a question. Any help would be appreciated. The following code (taken from the downloaded source code) is from the HelloClient.cs file (I deleted a few commented lines):

using System;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Activation;
using System.Runtime.Remoting.Lifetime;

namespace Wrox.ProCSharp.Remoting
{
   public class HelloClient
   {
      public static void Main(string[] args)
      {
         ChannelServices.RegisterChannel(new TcpChannel());
         object[] attrs =
            {new UrlAttribute("tcp://localhost:8086/Hello") };
      Hello obj = (Hello)Activator.CreateInstance(typeof(Hello),
               null, attrs);

    ILease lease = (ILease)obj.GetLifetimeService();
    if (lease != null)
    {
        Console.WriteLine("Lease Configuration:");
        Console.WriteLine("InitialLeaseTime: " +
                lease.InitialLeaseTime);
        Console.WriteLine("RenewOnCallTime: " +
        lease.RenewOnCallTime);
        Console.WriteLine("SponsorshipTimeout: " +
        lease.SponsorshipTimeout);
        Console.WriteLine(lease.CurrentLeaseTime);
    }

    MySerialized ser = obj.GetMySerialized();
    if (!RemotingServices.IsTransparentProxy(ser))
    {
       Console.WriteLine("ser is not a transparent proxy");
    }
    ser.Foo();
    MyRemote rem = obj.GetMyRemote();
    if (RemotingServices.IsTransparentProxy(rem))
    {
        Console.WriteLine("rem is a transparent proxy");
    }

    rem.Foo();

    System.Console.ReadLine();
    }
  }
}

I executed the sample and everything worked as expected, the server was active, the remote methods were called. So my question is: what's the need for the following line:

      ChannelServices.RegisterChannel(new TcpChannel());

I tried commenting it and everything worked exctly the same way! I see a need for registering a channel for the TCP client but no handle to it seems to be given by the previous code. Can anyone explain this to me?

Thanks in advance,
Miguel Barrosa

Sorry, I forgot to mention this. The previous post refers to the 3rd edition of the book.
