App hangs on first request if both SSL in Kestrel and IISIntegration are enabled

[danroth27]

If I enable both SSL in Kestrel and IISIntegration the app hangs on the first request when I run it in VS using IIS Express:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Logging;

using Microsoft.AspNetCore.Server.Kestrel;
using Microsoft.AspNetCore.Server.Kestrel.Core;
using Microsoft.AspNetCore.Server.Kestrel.Https;
using System.Security.Cryptography.X509Certificates;
using System.Net;

namespace mvc_individual
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var host = new WebHostBuilder()
                .UseKestrel(options =>
                {
                    options.Listen(IPAddress.Loopback, 44316, listenOptions =>
                    {
                        listenOptions.UseHttps("danroth27.com", StoreName.My, StoreLocation.CurrentUser);
                    });
                })
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseIISIntegration()
                .ConfigureAppConfiguration((context, configBuilder) => {
                    configBuilder
                        .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
                        .AddJsonFile($"appsettings.{context.HostingEnvironment.EnvironmentName}.json", optional: true);

                    if (context.HostingEnvironment.IsDevelopment())
                    {
                        // For more details on using the user secret store see https://go.microsoft.com/fwlink/?LinkID=532709
                        configBuilder.AddUserSecrets<Startup>();
                    }

                    configBuilder.AddEnvironmentVariables();
                })
                .ConfigureLogging(loggerFactory => loggerFactory
                    .AddConsole()
                    .AddDebug())
                .UseStartup<Startup>()
                .Build();

            host.Run();
        }
    }

    public static class KestrelServerOptionsHttpsX509StoreExtensions
    {
        public static ListenOptions UseHttps(
            this ListenOptions options,
            string subjectName,
            StoreName storeName,
            StoreLocation storeLocation)
        {
            var certStore = new X509Store(storeName, storeLocation);
            certStore.Open(OpenFlags.ReadOnly);
            var certificates = certStore.Certificates
                .Find(X509FindType.FindBySubjectName, subjectName, validOnly: false);

            var certificate = certificates.OfType<X509Certificate2>().First();

            return options.UseHttps(certificate);
        }
    }
}

@halter73 @JunTaoLuo @natemcmaster From a quick debugging on Dan's machine, it looks like PreferHostingUrls isn't working as expected.

We have a test for it right?

The ordering in Hosting is wrong. UseIISIntegration sets the option in ConfigureServices (or HostingStartupAssemblies), but WebHost reads the option before that. The fix is to read the option directly from config rather than via options, like we do for the urls.

@JunTaoLuo Can you file a new bug in Hosting, and add an integration test in this repo?

Closing as this was done in preview1.
