I am trying to make a notifyIcon by i have this: The type or namespace name 'NotifyIcon' could not be found (are you missing a using directive or an assembly reference?) and when i try to fix it using: using System.Windows.Forms; i have this error : The type or namespace name 'Forms' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?)
