I understand from the previous posts in this forum that the client support for PollingDuplexHttpBinding in previous versions of SL was
limited to silverlight clients only.
Is there any change in .NET4 / SL4 in this area for supporting full framework clients? We have a scenario where we need firewall-friendly callbacks to a non-SL client from a WCF web service. If folks have other recommendations for bindings that we could
consider, please share.
