Can a WCF Service provide publish/subscribe activity to a Linux-based C++ client application?

I have a WCF service written to provide certain functionality to intranet-based clients. This is easy when a client is running Windows. I want to implement the same functionality for my Windows clients that is available to my linux clients. My questions are?

How can I communicate t开发者_StackOverflow中文版o a linux c++ based client (supporting callback operations for a publish subscribe) type situation? I am aware of using SOAP over the HTTPBinding but is that the only way (does not support callbacks I believe)?

Would the same apply if I were using TCPBinding on the service-side? Currently, the service is set up using TCP but what are my options for the linux client communcation?

I read somewhere that messages can also be sent (via webservices I believe) in XML rather than SOAP? Which would be a better approach or how to determine which is a better approach?

I am trying to understand the options I would have for a WCF data service if I wanted to communicate with it from a linux client. I appreciate all your help.

Thank You,

Jeremy

On the linux side Mono is developing WCF functionality but it is not finished yet

On the c side there is a WCF template, but I think that it only supports basicHttpBinding
