Also during the second PDC keynote came the announcement of the previously announced RIA Services being given the name WCF RIA Services. WCF RIA Services simplify building multi-tier applications where the client tier is using Silverlight. WCF RIA Services are able to use all of the features of WCF while reducing the amount of work spent on service configuration, contract specification, data validation, and deployment.

A beta release of WCF RIA Services is available for both Silverlight 3 and Silverlight 4.
