Thank for the replay ( both you and Rodolfo ) but I'm a very new 
beginner with mono and c# development, so I'm sorry but I have to ask 
also what to do to add such a reference.
I suppose it should be a statement to add inside the code but I didn't 
found how do that.
Can you give me more details on that ?
