ASP.NET/MVC : The requested resource does not support http method 'GET'

Question

I have a method defined in ApiController. When the method is defined like this :

public IEnumerable<QuestionResponse> Get() 

Everything is fine. However I want to pass a parameter to that method but when I define that method as

public IEnumerable<QuestionResponse> Get(int parid) 

The response is a 405 "The requested resource does not support http method 'GET'".

When there's no parameter defined for the method then both of these urls are routed to the method :

/api/questionresponse/224809
/api/questionresponse

But when I define an argument to that method both of those urls result in a 405 .

Help ?

FWIW

• the request is being made from some jquery on a page served from within the same project
• I've based what I've done to date on this text http://www.asp.net/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api .
• the results I'm describing here are all when run from within Visual Studio 2015 .

If you check the route you can see the default template makes use of parameter {id}

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

So you need to change the controller signature to

public IEnumerable<QuestionResponse> Get(int id) 

Or write a Custom route to support parameter parid
