- Some best practices would be ignored/dropped in order to drive the main focus to the other concepts this article is about.
- We will not create a whole Web Application as this would include a lot of distractions. We would just use Console and Windows Forms apps.
- The code included into this article is for demonstration and explanation only. Before going to your production code, you need to apply some refactoring and…
