Query: A frustrated programmer

I thought I would be spending 21 days learning Visual Studio .NET, instead I have been spending much of the time working around bugs in the code examples. All of the code listings are suppose to have both VB.NET and C# listings. In one case there was no C# listing and converting the VB.NET code to C# was not easy. In another case an error in both the VB.NET and C# listing resulted in a form that had bogus data displayed and this form was shown in the book! This book is not for the beginner. It assumes you have a basic knowledge of SQL Server and XML. It lacks organization. Very poorly proofread.
