Assemblies / Serialization

You shouldn't use serialisation in your case because you deal with separate solutions that means separate application domains. use the MarshalByref class to comunicate between objects  in a sparate domains.

suppose that you have application client  that consumes an object myclass located in other application
first make use of the System.Net; and System.Remoting name spaces

then

derive your object from MarshalByRefObject
like this

// This is a type that will be
// marshaled by reference (MBR) if accessed remotely.
public class myclass: MarshalByRefObject
{
public myclass()
{ }

// This method takes an input string from the caller.
public void DisplayMessage(string message)
{ Console.WriteLine("Message is: {0}", message);}
// This method returns a value to the caller.
public string ReturnMessage()
{ return "Hello from the server!"; }
}
}

inorder to transfert this object you have to build a third parti witch is in fact the server that communicates the object to the client
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;


but don't forget to make of the assembly that holds my class in the server one, I mean in addition to those above namesapce you have to in clude

using namespace that contains of myclass

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
using  ........; /*Assembly of my class*/ ;

add this code to the server main method

// Register a new HttpChannel
HttpChannel c = new HttpChannel(14000);// you can use ports of your choice but they must not be used by other programs like 80 for http or 25 smtp
ChannelServices.RegisterChannel(c);
// Here singleton activation is used.
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(SimpleRemotingAsm.RemoteMessageObject),
"RemoteMsgObj.soap",
WellKnownObjectMode.Singleton);
Console.ReadLine();

in your application that consumes that data use this code to consume myclass object data

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
using  ........; /*Assembly of my class*/

Console.WriteLine("***** SimpleRemoteObjectClient started! *****");
Console.WriteLine("Hit enter to end.");
// Create a new HttpChannel.
HttpChannel c = new HttpChannel();
ChannelServices.RegisterChannel(c);
// Get a proxy to remote WKO type.
object rmtObj = Activator.GetObject(
typeof(SimpleRemotingAsm.myclass),
"http://localhost:14000/myclass.soap");
// Now use the remote object.
myclass data = (myclass)rmtObj;
simple.DisplayMessage("Hello from the client!");
Console.WriteLine("Server says: {0}", data.ReturnMessage());
Console.ReadLine();
