How do you add a new MediaType to the MediaTypeFormatters used by ASP.Net WebApi?

Question

I have an ASP.Net WebAPI project that will be returning JSON, but specifically HAL+JSON. I know I can write a custom MediaTypeFormatter to do this, but I plan on returning the same HAL formatted response even if you ask for plain JSON, so my question is:

Rather than writing a new MediaTypeFormatter for HAL+JSON, can I add a new media type ("application/hal+json") to the list of media types that the default WebAPI JsonMediaTypeFormatter recognizes?

Answer 1

Think I found my answer. In Global.asax:Application_Start(), I can do this:

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/hal+json"));
