I have a case where I need to transfer large amounts of serialized object graphs (via NetDataContractSerializer) using WCF using wsHttp. I\'m using message security and woul
Since nobody has put it out there, perhaps using WebSockets or long polling techniques may be able to solve this issue. I've only looked into these solutions briefly and haven't developed a solution around them but I wanted to propose these concepts for the record and I'll expand upon my answer at a later point if time permits.
The underlying idea would be to achieve something similar to how the idea of how the ChunkingChannel example works but while not requiring a full duplex channel which typically breaks the port 80 web based request/response model that is desirable to avoid having to make firewall and other related configurations for clients.

Update: After researching more on this it appears that by using WebSockets, which is known known as NetHttpBinding, that I would inherently not be solving the original request which is to use wsHttp in WCF with message security. I'm going to keep my answer here however as information for others who may be looking into an alternative.
