Can I use RIA services from WPF?

Question

Or do I need a Silverlight client?

Answer 1

Yes, RIA services can be used from WPF, or in fact any NET Framework client. However many of the client-side controls typically used with RIA are Silverlight specific, so your mileage may vary.

Answer 2

You may want to look at WCF Data Services too.

I'm still learning the differences so not quite yet ready to compare the two.
