Why you shouldn’t use a GUI designer in WPF and Silverlight

For some years, I am trying to convince people in my surroundings not to use the GUI designer for WPF and Silverlight. Some with success, some without. In my crusade to perfect software development for all users (not just you), I finally found some time and energy to create an example application and a video that shows why you shouldn’t be using the GUI designer to design GUI’s.
