In this article, (toward the end in the ‘Windows Communication Foundation’ section) the author suggests that a one way transmission in WCF is essentially UDP. Is this correct? Should I assume based off the content of this article that marking my service ops as ‘one way’ means I’m using UDP?

Furthermore, he’s suggesting using UDP in conjunction with WS-ReliableMessaging to negate the need to write those aspects of the transport protocol yourself… Ok, but if I want to leverage the performance benefits of UDP in a situation that warrants it, I should, as per this article’s suggestion, just use ‘one way’ and WS-ReliableMessaging and I’m good to go!? Sounds a little far fetched to me…

So what’s the deal here? What are the caveats of what this article is suggesting?

    No, you are misunderstanding the article. The article is saying two different things:

    1. WCF one way operations are somewhat analogous to UDP datagrams.

    2. WS-ReliableMessaging could be implemented on top of UDP if desired.

    Even one way operations require acknowledgements, retransmissions, and the like to make them reliable.
