This book was designed with one thing in mind: the way people learn the C# language. Seminar audience feedback helped me understand the difficult parts that needed illumination. In the areas where I got ambitious and included too many features all at once, I came to know—through the process of presenting the material—that if you include a lot of new features, you need to explain them all, and this easily compounds the student’s confusion. As a result, I’ve taken a great deal of trouble to introduce the features as few at a time as possible.
