Hi Sylvain. Do you divide your middle-tier into UI-Centric (client side) and Data-Centric (server side) business objects? If so then if your UI-C BOs are responding to KeyBoard, Change, etc., events from the UI then would early binding not be critical to performance? Or I guess in any case where your UI uses your BOs extensively?

What is C# ?
