跟踪已执行操作MVC和SinglaR的进度

Question

我有问题。我正在按照此处提到的方法进行操作：Progress bar for long running server calls in ASP.Net MVC，但是它不起作用。没有例外也没有错误，问题是什么也没做。为什么我的代码不向客户端报告进度？另一件事是我不知道为什么signalR无法生成脚本

<script src="~/signalr/hubs"></script>

控制器

ProgressHub.SendMessage("Iniciando proceso", 2);

启动类

using Microsoft.Owin;
using Owin;
using Microsoft.AspNet.SignalR;


[assembly: OwinStartup(typeof(DimexCEUI.Startup))]
namespace DimexCEUI
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            //ConfigureAuth(app);
            app.MapSignalR();
        }
    }
}

我的中心

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Web;
using Microsoft.AspNet.SignalR;

namespace DimexCEUI
{
    public class ProgressHub : Hub
    {

        public string msg = "Initializing and Preparing...";
        public int count = 1;

        public static void SendMessage(string msg, int count)
        {
            var message = "Proceso completado " + msg;
            var hubContext = GlobalHost.ConnectionManager.GetHubContext<ProgressHub>();
            hubContext.Clients.All.sendMessage(string.Format(message), count);
        }

        public void GetCountAndMessage()
        {
            Clients.Caller.sendMessage(string.Format(msg), count);
        }
    }
}

客户：

function StartInvoicing() {
    var progressNotifier = $.connection.progressHub;

    // client-side sendMessage function that will be called from the server-side
    progressNotifier.client.sendMessage = function (message, count) {
        // update progress
        UpdateProgress(message, count);
        alert(message);
    };

    // establish the connection to the server and start server-side operation
    $.connection.hub.start().done(function () {
        // call the method CallLongOperation defined in the Hub
        progressNotifier.server.getCountAndMessage();
    });
}

// Update the progress bar 
function UpdateProgress(message, count) {
    var result = $("#progress-data");
    result.html(message);
    $("#progress-count").html(count);
}
