Remoting client activation, method not found error   

I am using client activate remote object.
I register with RegisterActivatedClientType  code.
RemotingConfiguration.RegisterActivatedClientType(typeof(Remote.cTransfer), 
s_URL);
It works. I can call remote object methods.
Now I added new method 
Now I update the remote object, added new method Method B.
If I invoke this method it says method not found.
How do I make remote services load latest assembly??
