Description sornakumar 2015-08-28 12:21:21 UTC
When a URL like "http://localhost/Travel/Flight" is requested in a controller like:
    public class FlightController
        private readonly TestResponseGenerator _generator;

        public FlightController(TestResponseGenerator generator)
            _generator = generator;

        public IActionResult Index()
            return _generator.Generate("/Travel/Flight", "/Travel/Flight/Index");

        public IActionResult BuyTickets()
            return _generator.Generate("/Travel/Flight/BuyTickets");

incorrect action/controller are selected. There is no exception thrown but a wrong action/controller is selected. The exact same scenario worked fine in but fails in 4.3.0 (master/88d2b9d Wed May 27 15:09:54 PDT 2015).

I am not able to corner down on a particular area where things are going wrong but I am guessing something changed in "System.Reflection" which is causing this problem. Here is some code to help you debug further:

Generate method: https://github.com/aspnet/Mvc/blob/dev/test/WebSites/RoutingWebSite/TestResponseGenerator.cs#L26
Flight controller: https://github.com/aspnet/Mvc/blob/dev/test/WebSites/RoutingWebSite/Areas/Travel/FlightController.cs
