The advantage of using something like WCF is that the "passing" anomalies of some routers are handled for you. I am talking about checking deep packets that some routers that will identify the material that you send as “inappropriate” if it does not look like pure HTML.
On the other hand, working with WCF in C ++ can be interesting. Presumably this means that you are ready to write code as C ++ / CLI.
However, I think you will find that choosing a network infrastructure is less of a problem. Moreso network management logic will consume your time. If you are performing any kind of asynchronous network communication, make sure that you are well educated with a good government structure . Also pay attention to the C # port .
ps If you are not using managed clients with WCF, just remember that your messages must be serialized with XML properties / attributes in alphabetical order. Otherwise, you will receive unexplained errors. If I remember, zeros should be sent explicitly.
