With this channel I would like to share my knowledge of what I have learned in the last 10 years professionally as well as in private in the programming world with you. I will focus mostly on C# and Unity. With some small side trips to SQL and API's. A channel dedicated to programming, technology and game development tutorials. #Assharpdev ▬ Some Helpful Stuff▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Here are some good books in my opinion, some of which I own myself. Since I speak German as well as English, books for both languages are available. However, I think that it is a great advantage to know the English language, especially in terms of programming.
