server.urls Paramter Not Working On Kestrel Server for dotnet Command on ASP.NET Core RC2

Was struggling really hard with getting this command to work:

dotnet run -- --server.urls http://*:5000

Simple command, but it isn’t taking! Well I missed one major thing when upgrading from RC1 to RC2, I need to now pass configuration down to the Kestrel stack, to do that is pretty easy:

        public static void Main(string[] args)
        {
            var config = new ConfigurationBuilder()
                .AddCommandLine(args)
                .AddEnvironmentVariables(prefix: "ASPNETCORE_")
                .Build();

            var host = new WebHostBuilder()
                .UseConfiguration(config)
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseIISIntegration()
                .UseStartup<Startup>()
                .Build();

            host.Run();
        }

Needed to define the “config” variable and pass it to WebHostBuilder using UseConfiguration(). All fixed!
