I comparing the above frameworks, and note in ServiceStack that it can output different formats, not just JSON, or XML, but CSV, SOAP, Text and HTML. However, when I compare this with OpenRasta and Nancy, in their documentation, I don't find this mentioned explicity.
Therefore, has anyone had any experience of these frameworks, and if so, can they output more than just JSON and XML?
Further, can any of these frameworks be used as web service on their own and then consumed by say a WinForm application?
Cheers
