Query: Some important topics missing...

Its one of the best books, but surely not a Bible and Not a 5*. It DOES NOT cover all topics. Most importantly, Threads and Asynchronous calls are missing. No remoting or web stuff either, and not much on security.In essense, this is a very good book to get started but not as a reference for 'everything in .Net'. This covers basic types, text, strings, enums, exceptions, arrays, memory management..you get the idea, right?We at work, read through the entire book - and in the end, had to go to the O'Reilly book by Juwal Lowy for Threading, thread synchronization and async calls... So, If you are a Backend or middle layer developer, get Juwal Lowy and Richter. Between the two you will have most of .NET programming covered (other than web specific stuff)
