It covers many topics around Visual Studio.net. Its coverage of Debugging(Chap 3), Macros(Chap 8) are good.
One missing piece is Web Services with Visual Studio.net. I didn't find any related information in it. Also, serveral times, when I needed some information about Visual Studio.net, I couldn't find it in this book. Though I've been using VS.net for several months, I never needed most of the information in this book.
