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
If you still want to use Message Security, I would recommend you to use MTOM to optimize the network bandwidth that needs be used to transfer the messages, and also the chunking channel for using smaller memory buffers when security is applied. Otherwise, WCF will try to load the whole message in memory to apply security, and therefore you will get the Insufficient memory exception.
