WCF streaming a stream

[sathenzar]

Correct me if I'm wrong, but I thought when you enabled streaming on a WCF contract and returned a Stream, it literally streamed the data in chunkcs governed by the bindings on the buffer pool size. However in my testings it seems as if the response still reads the whole stream in at once then lets you use it. I was hoping for the ability to start streaming as soon as I called the function and start reading the byte data. Am I missing something here or did I read something wrong in the WCF documentation?
