ApiController Routing Isn't Working

Below I'm going to insert the code for the following:

It is my understand that what I'm doing here is 100% correct, and in fact I've verified that the code lines up with an example I found from Mike Wasson. Hopefully you can show me the way to getting this working!

Thanks all!

Global.asax

Below is the code that exists in the Global.asax and this method is called by Application_Start() which was generated by the template.

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

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

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

DatabasesController.cs

This is the ApiController, and it inherits from ApiController and was created by the template in Visual Studio. The databases field is declared as Database[] in the class.

public IEnumerable<Database> GetAllDatabases()
{
    return databases;
}

public Database GetDatabaseById(string id)
{
    return databases.Where(d => d.Name == id).FirstOrDefault();
}

Error

This is the error I'm receiving when I try to access it with what should be the default api path (as far as I understand it anyway...HA).

Server Error in '/' Application.

It looks like you need to upgrade your version of webapi from beta to RC!
