ASP.NET Web Api: The requested resource does not support http method 'GET'

Question

I've got the following action on an ApiController:

public string Something() {     return "value"; } 

And I've configured my routes as follows:

routes.MapHttpRoute(     name: "DefaultApi",     routeTemplate: "api/{controller}/{action}/{id}",     defaults: new { id = RouteParameter.Optional } ); 

In the beta, this worked just fine, but I just updated to the latest Release Candidate and now I'm seeing errors on calls like this:

The requested resource does not support http method 'GET'.

Why doesn't this work anymore?

(I suppose I could get rid of {action} and just make a ton of controllers, but that feels messy.)

Answer 1

If you have not configured any HttpMethod on your action in controller, it is assumed to be only HttpPost in RC. In Beta, it is assumed to support all methods - GET, PUT, POST and Delete. This is a small change from beta to RC. You could easily decore more than one httpmethod on your action with [AcceptVerbs("GET", "POST")].
