Guest blogger CRM MVP David Yack talks about what he has been doing in his spare time. :o)
In my spare time (ha!) for the last year I have been working on writing a book targeted to developing applications on CRM 4.0. Originally, the book was going to be a short book focusing on workflow but has grown to over 600 pages covering all developer centric topics. In the book I talk about everything from setting up a developer environment to using SilverLight with CRM. You can read the full press release on the book on MarketWatch.
CRM as a Rapid Development Platform is not a "user" book, it's a developer book. I might even go as far as saying a power admin that wants to understand more about what's going on would benefit as well. The book goes deeper into developer topics like client scripting, web services, plug-ins and workflow than any of the other books currently released.
