Re: Url.Route method throwing exception

<div id="reference-post-content" class="reply-comment">

I have done the following:

var _config = new HttpConfiguration();
_config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}");

var _controllerContext = new HttpControllerContext(_config,
   new HttpRouteData(new HttpRoute("DefaultApi")),
   new HttpRequestMessage(HttpMethod.Post, "http://localhost/api/contacts"));

contactsController.ControllerContext = _controllerContext;

Which I believe complies with my application set up:

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

However I am still getting the same error:

Value cannot be null.
Parameter name: name

</div> </div>

This may be bug in self host or null value in name paramter is not allowed in self host case. See the diffrence(from source),

web host case,

  if (string.IsNullOrEmpty(name))
        {
            return this.GetVirtualPath(requestContext, values);
        }

and self host case,

 if (name == null)
            {
                throw Error......
            }
