The title is deceptive, it's more than textbook Developer Reference

In "Developer Reference" one thinks first of all of pages of tables with dry attribute tables along with their description. So I was very surprised that this book is much more a thick, complete textbook for developing in SharePoint 2013, including Introduction to SharePoint and smaller, but complete example developments along with their source code. Still, there is not much literature on SharePoint 2013 Development, I own them all virtually and in my opinion this book is the best of all, I like it better than, say, the two Professional / Beginning SharePoint 2013 Development considerably. Good value for money in the circumference attached and moderate price also.
From there with a buy recommendation!
