Revisiting day 08

This is the revision day of our book. Of course, this is the last chapter of the book, but this is just the beginning for you to start exploring more C#-related stuff. On this day, we developed an application based on the Indian GST system. With the help of this application, we revisited all that you learned in this seven-day learning series, including attributes, reflections, C# 7.0 features, and so on.
