Using the correct font at design time solves the problem Josuegomes points out, because any container control that is created on the form will pick up the font used by the form at design-time.Besides the above advantages, this frees you from having to remember to modify the constructor for each form that you create and ensures consistency across all of the forms in your application, as well as giving you a place to put other common functionality.
