SignalR can keep communication with the client and Server on real time. It`s a very wonderful independent tool for MVC development. 

Here I just finished an example by myself . And try to deepen my understanding in it.

SignalR was supported by the windows server 2012 that under the IIS 8 and .NET Framework4.5 environment. In the backaround, it`s 

support the WebSocket.   

At first, just try to add the package by Nuget

1. Microsoft.AspNet.SignalR  

2.Microsoft.AspNet.SignalR.Client

 

@{    ViewBag.Title = "Home Page";}
    
    
    
    
     
        
          
     
    
     
        
      
            
       
            
       
        
      
    
     
    
     
        
      進捗率    
     
    
    
    
     
    

 

3. in view file support the last request as the source attacker.

You'd better bring the java script to your html file.

      進捗率    
     
    
    
    
     
    

4,   And a ProgressHub.cs as the following

 pasting

using Microsoft.AspNet.SignalR;using Microsoft.AspNet.SignalR.Hubs;using System.Threading.Tasks;using System.Threading;namespace WebApplication1{
       [HubName("progress")]    public class ProgressHub : Hub    {
           public int count = 1;        public static void SendMessage(string msg, int count)        {
               var hubContext = GlobalHost.ConnectionManager.GetHubContext
    
     ();            hubContext.Clients.All.sendMessage(string.Format(msg), count);        }        public void GetCountAndMessage(string msg)        {
               ProgressStart();            Clients.Caller.sendMessage(string.Format(msg), count);        }        private void ProgressStart()        {
               Task.Run(() => {
                   for (int i=1; i<=100; i++)                {
                       Thread.Sleep(500);                    SendMessage("処理中...", i);                }            });        }    }}
    

 5. Edit the Startup.cs file.

 pasting

namespace WebApplication1{
       public partial class Startup    {
           public void Configuration(IAppBuilder app)        {
               ConfigureAuth(app);            app.MapSignalR(); // ← この行を追加        }    }}
