I'm trying to enable a streamed response using Silverlight 4 and polling duplex, but I'm getting strange behaviour when the rate at which updates are sent to the client is greater than the maxOutputDelay, which results in no updates being sent.
For example, with a maxOutputDelay of 7 seconds, and 1 update sent every 10 seconds, everything works fine. But if I have a maxOutputDelay of 1 second, and an update sent every 500 milliseconds, the updates just sit on the server side and don't get sent to the client.
It's my understanding that setting transferMode="StreamedResponse" should send the updates immediately to the client, but this doesn't seem to be working.
Here's the binding in my Web.config for the web service:
This config is based on the information from this article: http://blogs.msdn.com/b/silverlightws/archive/2010/06/25/http-duplex-improvements-silverlight-4.aspx
Thanks.
