Can .NET Ria service push data from server to client?

问题

Can the .NET RIA Service automatically push data to the silverlight client without the client polling the server at all?

I want a feature similiar to wcf duplex polling.

Not currently. It's something they are thinking about for version2 apparently.

You can do it with WCF: .WCF Duplex with Silverlight
