将ASMX Web服务迁移到WCF

Question

We have developed the wcf service with the existing web service code. the existing customer wants to consume that service only changing the new url. They do not want to replace the proxy class. is it possible in any case.

The customer is able to consume the same with replacing the proxy and config. but he does not want to replace the proxy. please share ur comments whether it is possible or not.

Answer 1

You may be able to do this by configuring an endpoint using basicHttpBinding . I believe you will also need to force the use of the XML Serializer, and I don't know how to do that offhand, so someone else will have to help you with that. I'm concerned that there could still be small differences that would cause errors using the same proxy class.

On the other hand, if performance isn't the top consideration, you could create an ASMX service using the original class and method attributes from the old service. This ASMX service would then call the WCF service.

BTW, the ASMX service could call the WCF service on a fast endpoint. If they were running on the same server, they could use netNamedPipesBinding , for instance, but in any case could use netTcpBinding , which uses binary over TCP/IP. That would mitigate the performance difference from the extra hop.
