Today at MIX11, Brad Olenick announced RIA/JS, a jQuery client for WCF RIA Services. This is an early preview that we want to get your feedback on. Long before WCF RIA Services V1.0 was released, we started talking RIA Services support for AJAX; in fact, you can see the item here on the RIA Services Wish List (11th ranked as of today). We hope that you’ll grab this preview and let us know if you like the direction we’re going.
