We are looking at switching from using WCF for our service layer in applications to REST.
So far we are assuming that the way to do this is to use the WCF REST Start
We used WCF to implement a RESTFUL api, where we could post and receive data using XML, JSON and ProtoBuf. Same thing with GET.
However, once we looked at ASP.NET MVC we dumped WCF and are now using MVC to do the same thing with much more transparent code. There is some nice articles on google on how to do this. Our primary need was to give clients the option to serialize request and receive responses to XML, JSON, or Protobuf.
I would say WCF is dead to us. Long live MVC
