Question

Can somebody help with this? I have this controller:

public class CbpOutcomeController : ApiController
{
    // POST /api/CbpOutcome/1/ 
    public HttpResponseMessage PostCreateCbpOutcome(CbpOutcome co)
    {
        ... snip ...
        return resp_msg;
    }
}

And this route:

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "HubProfilePostRoute", // Route name
            "hub/{controller}/{action}", // URL with parameters
            new { controller = "Home", action = "Index" } // Parameter defaults
        );

        routes.MapHttpRoute(
            name: "ProfileByRegionApi",
            routeTemplate: "api/{controller}/Region/{region_name}"
        );

        routes.MapHttpRoute(
            name: "ProfileByGlobalPriorityApi",
            routeTemplate: "api/{controller}/GlobalPriority/{priority_name}"
        );

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

And when I make the POST to http://localhost:2515/api/CpbOutcome, with this JSON structure:

{ "Id":0, "Description":"This is a description", "DisplayOrder": 3, 
  "ModifiedBy":"Somebody's name here", "Cbp": { "Id": 163 }}

I get this message:

No type was found that matches the controller named 'CpbOutcome'.

—Edit—

See the spelling of the your API class.

public class CbpOutcomeController : ApiController

Then see the spelling of your URL:

http://localhost:2515/api/CpbOutcome

Notice the Cbp and the Cpb

—End Edit—

API Controller URL should reside inside the WebApiConfig.cs file.

Not inside the RouteConfig.cs file

Analyse the default template provide with VS2012 for a Web API project and you will see it.
