ResponseFormat for WCF in JSON and XML at the same time?

Question

When requesting an object for example using REST, is it possible to get the response in json and xml format or do I have to create UriTemplates that are something like:

[WebInvoke(UriTemplate="&format=json?user/{id}", ResponseFormat=WebMessageFormat.Json)]

[WebInvoke(UriTemplate="&format=xml?user/{id}", ResponseFormat=WebMessageFormat.Xml)]

The reason I ask is because I may need one format returned for an app on an android phone for example and another type returned for an app on a laptop.

Also, Can the methods have the same name such as Register or do I have to have one called:

RegisterJSON(User user) and another called RegisterXML(User user)

Answer 1

It is available out of the box in WCF 4 (.NET 4.0). Check AutomaticFormatSelectionEnabled property of WebHttpBehavior. You can also set this property from configuration. I showed the example here.
