WCF RIA Services Part 6 – Validating Data posted

Part 6 of my series on WCF RIA Services is now live here:

http://www.silverlightshow.net/items/WCF-RIA-Services-Part-6-Validating-Data.aspx

In this episode, I explore the awesome validation infrastructure of RIA Services, one of my favorite benefits of RIA Services. I show how to use the built-in validation attributes of the System.ComponentModel.DataAnnotations namespace on both the client and server side, how to use custom validation via attributes, how to invoke validation logic on the server side and return errors that get automatically associated with the entities client side, and how to use Invoke methods to call async validation logic from the client.

Check it out!
