This books primary author is Shaun Walker the inventor of Dot Net
The book covers the history and purposes of DNN and provides all
the technical details of how DNN works and why it works the way it
I was disappointed since it is more of a technical discussion of
Dot Net Nuke rather than a "how to" on DNN.
It's an excellent advanced discussion of DNN, but not very useful
when it comes to first setting up and using DNN.
Great book once you have some DNN experience.
