Yet another ASP.Net WebAPI route not found

First off I have read as many articles as I can find on this topic and installed several "route debug" plugins. I am more familiar with Java/Spring so I really have no idea how to debug this thing, using vs 2012. (I cannot anyway to make IISExpress print any debug much less the kind of the debug output I am used to with Spring/Tomcat.)

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

routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Legal",
action = "Index",
id = UrlParameter.Optional }
);
}
}


Now, I am able to hit the Index page via the default controller. However, I am trying to hit the URL /WebApi/Metadata/ based on the following controller:

[BreezeController]
public class WebApiController : ApiController {
private readonly EFContextProvider<BankruptcyDbContext> _contextProvider =
new EFContextProvider<BankruptcyDbContext>();

[HttpGet]
public string Metadata() {
return _contextProvider.Metadata();
}
}


The "Route Debugger" says that my requests for /WebApi/Metadata, /WebApi/Metadata/, /WebApi/Metadata/0, and more should "match" but all I get is 404.

Edit1: I finally found the trace logs and got a little more detail:

The controller for path &amp;#39;/WebApi/Metadata&amp;#39; was not found or does not implement IController

Answer

Be sure you are using the current latest version of Visual Studio 2012 with Update 2 etc.. You should not only have a RouteConfig.cs file in App_Start, but also there is a WebApiConfig.cs file

So While Normal MVC routes use the RouteConfig class

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

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

The Web API is using the WebApiConfig , which is stubbed out with the out of the box code suggested above in the static class WebApiConfig:

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