ASP.NET Web API 2 custom routing to specific method

Question

How can I configure routing in ASP.NET Web API to route it to specific method in controller with GET method?

http://mysite/healthcheck

Registration in WebAPiConfig looks like this:

    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "HealthCheck",
        routeTemplate: "healthcheck",
        defaults: new { action =" DefaultAction" }
    );

The controller looks like this:

[RoutePrefix("healthcheck")]
public class HealthCheckController : ApiController
{
    [HttpGet]
    [ActionName("DefaultAction")]
    public HttpResponseMessage GetHealthCheckStatus()
    {
        return Request.CreateResponse(HttpStatusCode.OK);
    }    
}

I get Not Found instead of Ok when hitting that URL. Any help would be appreciated

UPDATE Thank you for all the suggestions, I checked them all and none works. The route debugger shows no matches. I am putting this on hold for a while.

In your Startup.cs register attribute routes:

config.MapHttpAttributeRoutes();

And in the controller:

[RoutePrefix("healthcheck")]
public class HealthCheckController : ApiController
{
    [HttpGet]
    [Route]
    public IHttpActionResult GetHealthCheckStatus()
    {
        return Ok();
    }
}
