On our services, we configure several endpoints, allowing us to publish the same interfaces to SOAP 1.1 and 1.2 clients and HTTP clients consuming either XML or JSON. Now that the WCF REST team has been merged into the ASP.NET team to create the Web API stuff, what will this mean for us in the future? Will it still be supported to expose WCF interfaces as XML/JSON services? Should we move the REST endpoints to the Web API framework? Will this be the last shift of the MS REST stack?

Good question. I don’t work for Microsoft and I don’t have any inside information but my understanding is that WCF will be able to expose XML and JSON forever. In fact if you are merely exposing JSON or XML endpoints you are not doing REST. The real question is do you use the HTTP verbs (DELETE, PUT, POST, GET) as part of your API or you are simply exposing methods that are equivalent to your SOAP methods. If you are using the HTTP verbs it may be a good long-term strategy to migrate the REST part to WebAPI. If you are not then you can happily use WCF (go ahead tell your cusomers you are using REST for marketing reasons, to marketing people it’s just a buzzword anyway).
If you are using the HTTP verbs it is not that hard to have both WCF and WebAPI. All you need to do is remove all logic from the service itself and expose it as a business layer methods. Then both kids of services can use these methods, call them in the appropriate way and shape the results.
