Apart from that you'll learn some very important things like the problem of types substitution. You'll learn about the fundamental problems related to processing date and time values. Believe me you'll be astonished!

This course is built in a manner of a game. I'll show you code examples in Visual Studio and ask to answer the question related to that code example. You'll have some time to come up with your own answer and after that we continue. Puzzles gotchas and cautionary tales are presented here to frighten and inspire you! Regardless of your current skills you'll remember things you've forgotten learn things you didn't know and become a more robust programmer.
