Is there a particular reason why so many have chosen to target their tools at public fields rather than properties? My personal feeling is that p...
I have created a class called ProductionDataUserControlBase and it derives from class UserControl. This base class has no XAML. Its purpose is to act as a base class for a grid that I encapsulate inside the class so that it can be modified when the class is inherited later. Inside the constructor of the base class, I also create the colu...

Or...
