ASP.net web api 2 Route-Attribute not working

I've the following problem, my route attribute is not working.

I have the following action:

[HttpGet]
[Route("~api/admin/template/{fileName}")]
public HttpResponseMessage Template(string fileName)
{
    return CreateHtmlResponse(fileName);
}

and i want to access the action like .../api/admin/template/login.html, so that Template get login.html passed as the file name.

But i alsways get: No HTTP resource was found that matches the request URI 'http://localhost:50121/api/admin/template/login.html'.

The following request works: /api/admin/template?fileName=login.html

Does anyone know, what i am doing wrong with my routing?

EDIT:

My route configuration

config.Routes.MapHttpRoute(
                    "API Default", "api/{controller}/{action}",
                    new { id = RouteParameter.Optional });

Verify that you are using System.Web.Http.RouteAttribute and not System.Web.Mvc.RouteAttribute

In my case, I added Route("api/dashboard") to api controller. Changed it to RoutePrefix("api/dashboard") . And it works perfectly. Also you need config.MapHttpAttributeRoutes(); in webapiconfig.cs

Check your Route attribute's namespace. It should be System.Web.Http instead of System.Web.Mvc.

With my Web API 2 project I had to add a [RoutePrefix("events")] to the controller for it to pickup the action route attribute.

You have to call MapHttpAttributeRoutes() so that the Framework will be able to walk through your attributes and register the appropriate routes upon application start:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

        // you can add manual routes as well
        //config.Routes.MapHttpRoute(...
    }
}

See MSDN

Try this routing in your WebApiConfig

        // Web API routes
        config.MapHttpAttributeRoutes();

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

You have to add RoutePrefix.
