Using the newer ASP.NET Web API, in Chrome I am seeing XML - how can I change it to request JSON so I can view it in the browser? I do believe it is just part of the request headers, am I correct in that?
I just add the following in App_Start/WebApiConfig.cs class in my MVC Web API project.
config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html") );
That makes sure you get json on most queries, but you can get xml when you send text/xml.
If you need to have the response Content-Type as application/json please check Todd's answer below.
