I am working as a developer, and I like programming very much.

My hobby is to swim, play guitar and listening music. I want to go Switzerland.

I like to help people.

try with this code

[RouteArea("AreaName", AreaPrefix = "Cloud/Hosting")]
[RoutePrefix("RoaringPenguin")]
public class SampleController : Controller
{
    [Route("Manage/Exclusions")]
    public ActionResult Exclusions()
    {
        return View("Exclusions");
    }
}


or

[RoutePrefix("Cloud/Hosting/RoaringPenguin")]
public class RoaringPenguinController : PortalControllerBase
{

    [Route("Manage/Exclusions")]
    public ActionResult Exclusions()
    {
        return View("Exclusions");
    }

}
