Query: Mistakes Errors and Wasted Time

This book has nothing to do with professional!I spend hours to get rid of the "bugs" this book put into my programs. A lot of mistakes throughout the whole book.And also the topics are only scratching the surface and one is not really learning something (new).There are a lot of C# books out there - don't buy this one.
