Error with WebApi 2.0 RouteAttribute
10,335
Solution 1
Please remove
GlobalConfiguration.Configure(x => x.MapHttpAttributeRoutes());
from Global.asax.
And then call MapHttpAttributeRoutes
in the WebApiConfig.cs
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
}
Solution 2
In my case, I was getting this error because I was configuring Autofac before WebApi:
GlobalConfiguration.Configure(WebApiConfig.Register);
GlobalConfiguration.Configure(AutofacConfig.Register);
Changing the order got me past that issue:
GlobalConfiguration.Configure(AutofacConfig.Register);
GlobalConfiguration.Configure(WebApiConfig.Register);

Here's my Global.asax
protected void Application_Start() { RegisterRoutes(); } private static void RegisterRoutes() { AreaRegistration.RegisterAllAreas(); GlobalConfiguration.Configure(WebApiConfig.Register); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); GlobalConfiguration.Configure(x => x.MapHttpAttributeRoutes()); GlobalConfiguration.Configuration.EnsureInitialized(); }
Here's my Web Api controller
[RoutePrefix("api/admin/users/")] public class UsersController : ApiController { [Route("get")] public IQueryable<User> GetUsers() { return db.Users; } }
And here's the error I get when I navigate to localhost:123/api/admin/users/get
The object has not yet been initialized. Ensure that HttpConfiguration.EnsureInitialized() is called in the application's startup code after all other initialization code.
I have no idea what I'm doing wrong here. I believe that I'm doing everything properly for the new WebApi 2.0 way, but I'm missing something.
Thanks in advance.
Update
Here's the stack in-case it helps
at System.Web.Http.Routing.RouteCollectionRoute.GetRouteData(String virtualPathRoot, HttpRequestMessage request) at System.Web.Http.WebHost.Routing.HttpWebRoute.GetRouteData(HttpContextBase httpContext)
