WCF - Advice Required

I am starting a new webservice project which will be consumed by multiple consumer applications done in different technology like ASP, ASP.Net and PHP. I am planning to develop this service as a WCF service. I am new to WCF and I understand WCF is like umbrella tech which has all the features for developing a distributed SOA applications.

I would like to get your advice on whether my choice of opting WCF service over classic asmx service is correct. The consumer applications are existing application done different technologies as I said before. This service is a simple service that creates and updates user information in a centralized DB. If my decision of choosing WCF is correct, then please let me know if there are any specific things I need to consider so that the existing application c开发者_JS百科an consume my WCF service without any hiccups. In other words, I can provide a asmx service for this which they can consume directly without any issues (and currently they are consuming some of our asmx service. Since the current requirement is new I want it to be done with WCF). Likewise, the consumer should be able to consume my service like they consume asmx service.

I am asking this question because WCF provides additional features like security, etc. and hence the consumers should also follow the practice to communicate with the service. Any advice is highly appreciated.

You probably want to use BasicHttpBinding in your WCF service and, although I'm not a PHP developer, I understand that PHP 5 has a SOAP library that can be used to create a service proxy based on the WSDL document exposed by the WCF service, assuming metadata exchange is enabled.
