Remarks

The size of the messages that can be received on the wire by clients using the PollingDuplexHttpBinding class is bounded by the amount of memory allocated for each message. This bound on message size is intended to limit exposure to DoS-style attacks.

There is also a MaxBufferSize property on the PollingDuplexHttpBinding that gets or sets the maximum size for a buffer on the client that receives messages from the channel.
