"W8.1 C# Cheat Sheet Vol.1" by Moalla Ilani

After a long experience with new developer students, I have seen some are thirsty for very basic codes to startup their first apps. Some spend hours on search engines to find the codes they need from open source websites, and from professional point of view, being familiar with search engines is a great talent to have, while other fresh students are still not familiar and may give up from first time.

So cheers this is a safe place to start, this cheat sheet is full of very basic and useful C# windows 8 codes that will help you run your first apps, and you will always stay in need for it whatever professional you are. Of course I may miss some codes you may be waiting for, please feel free to tell me about in order to add them. So before beginning, I recommend everyone to save this cheat sheet on their desktop, in a notepad.txt file, and continue on adding some useful codes to it for future daily use, so that you save time and be more productive.
