I am still reading the book but so far I have found the author to have done a very good job describing the C# Language.  I am having a very easy time reading thing book due to his great examples and how he describes everything, though some things can get a little wordy but what programming book isn't. I definitely recommend this book for anyone looking to learn C# or further their knowledge in C#.
