My main concern is that it's coverage of core C# is somewhat skimpy. Important subjects such as data types, delegates, interfaces, and polymorphism are either not covered at all, or mentioned just in passing. So you are still going to need an in depth book on core C#. I recommend "C# Primer Plus", which I believe you should read before this one. Nothwithstanding some overlap between the two, they complement each other very nicely. This one will smooth the transition from core C# to usage of the bread & butter classes that are included in .NET.
