Question

我有一个示例的asp.net核心应用程序，其自定义的IServer接口实现如下：

namespace AspNetCoreAppWithOwinHttpListenerServer
{
    public class Program
    {
        public static void Main(string[] args)
        {
            IWebHost host = new WebHostBuilder()
                .UseHttpListener()
                .UseIISIntegration()
                .UseStartup<Startup>()
                .Build();

            host.Run();
        }
    }

    public class OwinHttpListenerServer : IServer
    {
        private IDisposable _HttpListenerServer;

        public IFeatureCollection Features { get; } = new FeatureCollection();

        public OwinHttpListenerServer()
        {
            Features.Set<IServerAddressesFeature>(new ServerAddressesFeature());
        }

        public void Start<TContext>(IHttpApplication<TContext> application)
        {
            Func<IDictionary<string, object>, Task> appFunc = async env =>
            {
                FeatureCollection features = new FeatureCollection(new OwinFeatureCollection(env));

                TContext context = application.CreateContext(features);

                try
                {
                    await application.ProcessRequestAsync(context);
                }
                catch (Exception ex)
                {
                    application.DisposeContext(context, ex);
                    throw;
                }

                application.DisposeContext(context, null);

            };

            appFunc = OwinWebSocketAcceptAdapter.AdaptWebSockets(appFunc);

            Dictionary<string, object> props = new Dictionary<string, object>();

            props["host.Addresses"] = Features
                .Get<IServerAddressesFeature>()
                .Addresses
                .Select(add => new Uri(add))
                .Select(add => new Address(add.Scheme, add.Host, add.Port.ToString(), add.LocalPath).Dictionary)
                .ToList();

            OwinServerFactory.Initialize(props);

            _HttpListenerServer = OwinServerFactory.Create(appFunc, props);
        }

        public void Dispose()
        {
            _HttpListenerServer?.Dispose();
        }
    }

    public static class OwinHttpListenerWebHostBuilderExtensions
    {
        public static IWebHostBuilder UseHttpListener(this IWebHostBuilder builder)
        {
            return builder.ConfigureServices(services =>
            {
                services.AddSingleton<IServer, OwinHttpListenerServer>();
            });
        }
    }
}

没有IIS就可以正常工作，但在IIS或IISExpress上运行会导致VSIISExeLauncher.exe“无法侦听给定端口”。

如何让自定义服务器与IIS兼容？提前谢谢。

自定义IServer实现不适用于IISIntegration
