Signalr 2应该在Windows 10，kestrel和aspnet core 1.0上使用websockts

Question

在启动时使用以下内容

        app.UseWebSockets();

        app.Map("/signalr", signalrApp =>
        {
            signalrApp.UseKatana(config =>
            {
                config.RunSignalR(new HubConfiguration
                {
                    EnableDetailedErrors = true,

                });
            });
        });

和一个简单的中心

public class MyHubBroadcaster : Hub
{
     public void Test()
    {
        Clients.All.addContosoChatMessageToPage("a", "b");
    }
}

并启动信号器

var connection = $.hubConnection();
connection.logging = true;
var contosoChatHubProxy = connection.createHubProxy('myHubBroadcaster');
contosoChatHubProxy.on('addContosoChatMessageToPage', function (userName, message) {
    console.log(userName + ' ' + message);
});
console.log(connection);
var promise = connection.start();
promise.done(function () {
    console.log('Now connected, connection ID=' + connection.id);
    setInterval(() => {
        contosoChatHubProxy.invoke('test').done((d) => console.log(d));
    }, 10000);
})
promise.fail(function () { console.log('Could not connect'); });

negotiantion返回TryWebSockets = false

我错过了什么或应该这样做吗？

main.cs

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

            host.Run();
