I should note that I helped with editing the book and I know the authors. But I still think this is the best book of its type.
Yes, I agree that it's the best present book in its category, especially when this kind of book never been written before. But I also believe it's necessary to point out that You need to know Your stuff in order to take advantage of its content.

BTW, who did the technical reviewing of the VSTO's and XLL's chapters?

Personally I was disappointed with some chapters, especially the Database-chapter which I believe could have been much better if it had been targeting SQL Server and with an another approach. After all, Mr Bovey obviously work with SQL Server and it would have been nice to take part of his experience in this ares.

FYI, I have had a detailed discussion about the book with Mr Bullen.

Kind regards,
