using Owin;

[assembly: OwinStartup(typeof(Apps.Web.Core.Signalr.StartupSignalr))]

namespace Apps.Web.Core.Signalr
{
    public class StartupSignalr
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
        }
    }
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.AspNet.SignalR;

namespace Apps.Web.Hubs
{
    public class ChatHub : Hub
    {
        public void Hello()
        {
            Clients.All.hello();
        }
        public void Send(string name, string message) {
            Clients.All.addNewMessageToPage(name, message);
        }
    }
}

    ViewBag.Title = "Chat";
    Layout = "~/Views/Shared/_Index_Layout.cshtml";
}

<h2>Chat</h2>
<div class="container">

            var chat = $.connection.chatHub;
            // Create a function that the hub can call back to display messages.
            chat.client.addNewMessageToPage = function (name, message) {
                // Add the message to the page.
                $('#discussion').append('<li><strong>' + htmlEncode(name) + '</strong>: ' + htmlEncode(message) + '</li>');
            };
            // Get the user name and store it to prepend to messages.
            $('#displayname').val(prompt('Enter your name:', ''));
            // Set initial focus to message input box.
            $('#message').focus();
            // Start the connection.
            $.connection.hub.start().done(function () {
                $('#sendmessage').click(function () {
                    // Call the Send method on the hub.
                    chat.server.send($('#displayname').val(), $('#message').val());
                    // Clear text box and reset focus for next comment.
                    $('#message').val('').focus();
                });
            });
        });
        // This optional function html-encodes messages for display in the page.
        function htmlEncode(value) {
            var encodedValue = $('<div />').text(value).html();
            return encodedValue;
        }
