+Summary: .NET Remoting example bug
+
+Description of Problem:
+
+I've been trying a little example I got from C# Professionnal 2nd Edition
+Book, which is running on the MS.NET Plateform with no bugs.
+The same example with mono is crashing when Activator.GetObject() method is
+called from the client. The .NET Remoting server is running fine.
+
+
+Steps to reproduce the problem:
+Here are the respective source of the object used byt both the client and
+the server, the server, and of course the client :
+
+##### OBJECT FROM HERE #####
+using System;
+
+public class Hello : System.MarshalByRefObject
+{
+	public Hello()
+	{
+		Console.WriteLine("Hello constructor called");
+	}
+	
+	~Hello()
+	{
+		Console.WriteLine("Hello destructor called");
+	}
+	
+	public string Greeting(string name)
+	{
+		Console.WriteLine("Hello.Greeting() called");
+		return("Hello, " + name);
+	}
+}
+##### OBJECT ENDS HERE #####
+
+##### SERVER FROM HERE #####
+using System;
+using System.Runtime.Remoting;
+using System.Runtime.Remoting.Channels;
+using System.Runtime.Remoting.Channels.Tcp;
+
+class MainClass
+{
+	[STAThread]
+	public static void Main(string[] args)
+	{
+		TcpServerChannel channel = new TcpServerChannel(8086);
+		ChannelServices.RegisterChannel(channel);
+		
+		RemotingConfiguration.RegisterWellKnownServiceType(
+			typeof(Hello), "Hi", WellKnownObjectMode.SingleCall);
+			
+		Console.WriteLine("Hit to exit!");
+		Console.ReadLine();
+	}
+}
+##### SERVER ENDS HERE #####
+
+##### CLIENT FROM HERE #####
+using System;
+using System.Runtime.Remoting.Channels;
+using System.Runtime.Remoting.Channels.Tcp;
+
+class MainClass
+{
+	[STAThread]
+	public static void Main(string[] args)
+	{
+		ChannelServices.RegisterChannel(new TcpClientChannel());
+		Hello obj = (Hello)Activator.GetObject(typeof(Hello),
+"tcp://localhost:8086/Hi");
+		
+		if(obj == null) {
+			Console.WriteLine("could not locate da serveur !");
+			return;
+		}
+		for(int i=0; i<5; i++) {
+			Console.WriteLine(obj.Greeting("John Doe"));
+		}
+	}
+}
+##### CLIENT ENDS HERE #####
+
+Actual Results:
+
+Actually, the server is running fine, only the client crashes with that
+exception stack trace :
+
+##### Exception from the client : Begin #####
+$ mono bin/Debug/Client.exe
+
+Unhandled Exception: System.NullReferenceException: A null value was found
+where an object instance was required.

+in <0x0000e> System.Activator:GetObject (System.Type,string)
+in <0x00047> MainClass:Main (string[])
+##### Exception from the client : End #####
+
+
+Expected Results:
+
+the expected resuls from the client are :
+
+##### Expected Client Results #####
+Hello, John Doe
+Hello, John Doe
+Hello, John Doe
+Hello, John Doe
+Hello, John Doe
+###################################
+
+and the server should give also
+##### Expected Server Results #####
+Hit to exit!
+Hello construtor called
+Hello construtor called
+Hello.Greeting called
+Hello construtor called
+Hello.Greeting called
+Hello construtor called
+Hello.Greeting called
+Hello construtor called
+Hello.Greeting called
+Hello construtor called
+Hello.Greeting called
+###################################
+
+How often does this happen?
+
+For now it's happening all the time with this configuration.
+
+
+I hope this would help you to debug this part of Mono :)
