Query: Nonsense

This book lost the ground of its course. Not good enough on C#, very little .Net framework, and gives only simple things about Windows programming and other key areas. One of the two big problems is beginner can't use the book. It's very difficult to follow it. There's no complete codes and instructions to get the pictures of the samples.The other big problem is it's too simple for experienced programmer. They can't get any decent lessons, or tips. What a reference!Obviously the auther had not much experience in developing applications, and poor teaching.Microsoft needs to clean dead woods to keep reputation. They needs to publish good books link Thinking in Java, Java Swing. Not bunch of Core Reference craps.
