This is rather a minor improvement, but I bet it will save code lines for some advanced XAFers who touch the internals of the XPO data layer created by XAF for various low-level database-specific customization like setting connection timeouts, changing default schemas, enabling and customizing caching, service end-points, etc. Check out this updated article for some example code showing the new approach in action.

Frankly speaking, this is quite low-level and rarely needed stuff, so we have not yet have it covered in the online docs, only in KBs. So, please refer to my 

How to customize the underlying database provider options and data access behavior in XAF article to learn more about it. Should you have any questions or additional usability suggestions, please let me know.
