Performance of asp.net WebAPI vs. asp.net MVC controller emmiting JSON?

Question

有谁知道使用WebAPI是否有性能优势，而不仅仅是使用返回JSON的MVC控制器？

Answer 1

I think the benefits are more related to flexibility than performance. You can implement a rest service using the MVC way, but the Web API provides a cleaner model: the actions are implicit in the HTTP verbs, the content can be delivered both in JSON and XML, there is native support to return an IQueryable< T > (this can be seen as a small performance improvement), and it can be integrated with an ASP.NET Web Forms application (or even a console app, with no ASP.NET at all).
