Web API: Content in HttpResponseMessage

Question

In one of my Get request, I want to return an HttpResponseMessage with some content. Currently I have it working as follows:

var header = new MediaTypeHeader         


        

Answer 1

HttpResponseMessage was removed after Beta. Right now, instead of a typed HttpResponseMessage we have a typed ObjectContent

If you manually create HttpResponseMessage using its default parameterless constructor, there is no request context available to perform content negotiation - that's why you need to specify the formatter, or perform content negotiation by hand.

I understand you don't want to do that - so use this instead:

HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, objInstance);

That would create the response message relying on the content negotiation performed against the request.
