I have just updated Extending A LightSwitch Application with SharePoint Data for Beta 2. I reshot all the screens and have made some minor changes to both the text and the narrative. There are two primary differences. The minor change is that I need to add code to enable editing of data in two different data sources. The more significant change is in what I need to do to create a one to many relationship between Courses in SQL Server and KBs in SharePoint.

I have now updated all but one of Beta 1 posts. One more to go.
