Difference Trolsen Programming language C#7 .net core 8 edition and CLR via C# in your subjective experience?

Question

Books

I study according to Troelsen, I heard a lot about CLR via C # Richter, I want to hear a person who dealt with them, and the lvl up of a person after reading a person of these (one of these) books

Answer 1

Troelsen it is, as it were, for beginners and about the language itself + frequently used classes from BCL.
Richter, he is about the internal structure and not quite about the language, but rather about the internal structure of the CLR with examples in c #. A lot of attention is paid to performance, locks, multithreading. I wouldn't recommend this book for the first time, and for the second one, too. But reading and understanding it can be considered a transition to a new level of professionalism. At first I read it - the brain was boiling and I thought: well, ok, later means. Then later again. And then the experience accumulated and I read it. And from time to time I look, re-read the right places. Richter and Skit.
