Web Service Backward compatability

[jonathan_phang]

Hi...

I have a bit of a problem (Which is partly my fault...) but anyway, wondering if anyone can save my bacon at work...

Way back, i developed an XML web service which was agreed with multiple clients and they have developed hardware that will submit biometric data via web service... Okay all is fine...

Except, the Web services that I developed have been upgraded to WCF services... but I havent been able to let the clients know (Cant really go into the details of this here).

But basically, is it possible for my WCF service to accept input from all the client machines? The schema for the data hasnt changed, just the move from xml web services to WCF.

I'm sure that there is something that i can do with bindings etc - but i really dont know enough at the moment, and am running out of time...

Any help would be greatly appreciated!

I don't get your question?

If you've got exactly the same interface over WCF, you can make it look like exactly the same webservice you where hosting via IIS or HTTP.SYS? Was that the question?

Sorry I've been a while getting back to you...

The thing is that i cant really get the clients to change anything (or much) on their hardware, so I am researching whether the changes can just be made on the new WCF service.

I have tried out a few things by using an old test client (which simulated the hardware and makes a web method call to the OLD xml service) and tried to get it to communicate with my new WCF services. Understandably getting contract mismatch errors, but trying to think about what to try next. Ideally, I would love to be able to just say "Just change the URL that the device submits data to" and then let WCF handle the rest, but I know its not going to be that easy really...

Sorry about the lack of detail in the questions - probably highlights my inexperience!

Thanks for any other comments
