Mike James, Founder and Chief Editor of I Programmer is a prolific author. In Deep C#: Dive Into Modern C#, published in September 2021, he provides a “deep dive” into various topics that are important or central to the language. By exploring the motivation behind these key concepts, which is so often ignored in the documentation, the intention is to be thought-provoking and to give developers confidence to exploit C#’s wide range of features.
