New Dynamics CRM book
Some friends of mine Dave and Julie Yack put together a very good book targeting techies ramping up to develop for Dynamics CRM 4.0. Dave wrote the content and Julie did the editing. I had the privilege of tech reviewing several chapters as well, so that was pretty cool.
If you are starting out with Dynamics or you want to increase your knowledge, then definitely go to the CRM book site and pick up the book. It’s well worth the money. There is 645 pages of good content that hit every major aspect of the Dynamics framework.
