After getting the images downloaded and setup, I've started to develop.  After getting over a few minor bumps, I'm underway.  I've used SqlMetal to generate entity classes from the DB Schema.  Initially, the classes weren't marked as datacontracts.  This is because I didn't use the /Serialization:Unidirectional switch.  After I regenerated the entity classes, I'm in business.  My WPF application binds to the results of a WCF call that retrieves data using Linq to SQL.
