You can go for Reflection... You can read a dll using reflection
Assembly a = Assembly.Load("helloworld");

Pass this object to another app.

hmm I don't know how to call later methods in another application if I good using it. I have server and client app. on server I have my class HelloWorld(this class can be in DLL what using server but its not that important), I just want to return this class to client app as assembly, on RemotableObject class I have only interface with method what returns this assembly class. Check my code... remote client have error during Assembly RemoteClass = objget.GetClass();
Could not load file or assembly 'HelloClass, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

why? I can't send my class/dll to another app and use thier methods?
server app:
...
using HelloClass;
 
namespace RemoteServerApplication
{
    public class HelloServer : MarshalByRefObject, IExecute
    {
 
        public Assembly GetClass()
        {
            Assembly a = Assembly.Load("HelloClass");
            return a;
        }
 
    }
}
 
HelloClass in dll file(referenced only to server):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace HelloClass
{
    public class HelloWorld
    {
        public void TestMe()
        {
            Console.WriteLine("Test string what will be writen in client.");
        }
    }
}
 
remotable object with interface(referenced to client and server):
public interface IExecute
    {
        Assembly GetClass();
    }
 
 
client gets this assembly:
IExecute objget = (IExecute)Activator.GetObject(
                    typeof(IExecute), "tcp://localhost:8085/RemoteTestRef");
            if (objget == null)
                Console.WriteLine("Could not locate server");
            else
            {
           
                Assembly RemoteClass = objget.GetClass();
}
