Cannot provide REST XML, REST JSON and SOAP properly via WCF-only configuration

I want to be able to create a WCF service that provides the following:

• POINTS JSON
• RESTfully provides XML
• Provides SOAP
• Other bindings as needed

The key point here is that I want to do this all through configuration , and only one function written in code for each method required, instead of having to code separately ResponseFormat=ResponseFormat.Json

or ResponseFormat=ResponseFormat.Xml

above separate functions for RESTful methods. I've done a lot of research and I can't seem to find anything solid if it's possible solely by configuration.

The weird thing is, when I build a project, the RESTful methods work when I access them via the url, but the WSDL throws an error - that is, if someone wants to reference / consume the service via SOAP, it will fail when the WSDL import step.

Below is the code for the service as well as the configuration and the service is hosted locally for testing at http: // localhost / WCF . The following 2 RESTful calls succeed and return successful XML and JSON in the browser:

local / WCF / service1.svc / json / students

local / wcf / service1.svc / leisure / students

But, if I call http: //localhost/WCF/service1.svc? Wsdl I get below error. If I remove one of the webhttpBinding endpoint configurations, the WSDL works and displays correctly, and therefore can be referenced.

Is it not possible to have multiple webHttpBindings in the configuration (i.e. has to be done with separate methods and attributes like ResponseFormat=ResponseFormat.Json

) to generate the WSDL? Or am I configured incorrectly here?

Any help that would be appreciated, it would be much easier to do this via config, which is additional functionality with the specified serialization. Thank.
