$.connection.(hubname) is undefined. Signalr/hub 501(not implemented) - asp.net-mvc-4

Question

I have a MVC 4 application which has a register page.
The code for hub is as follows:-
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using SignalR.Hubs;
[HubName("messageHub")]
public class MessageHub : Hub
{
/// <summary>
/// Broadcast the message to all clients
/// </summary>
/// <param name="message">message to be broadcasted</param>
public void Broadcast(string message, string messagetype, string messagetitle)
{
this.Clients.showMessage(message, messagetype, messagetitle);
}
public void Getsubscription()
{
}
}
Similarly, the JS hub code is:-
<script type="text/javascript" src="#Url.Content("~/Scripts/json2.js")"></script>
<script src= "#Url.Content("~/Scripts/jquery.signalR-0.5.2.js")" type="text/javascript"></script>
<script src="#Url.Content("~/signalr/hubs")" type="text/javascript"></script>
<h2>Index</h2>
<script type="text/javascript">
$(document).ready(function () {
//Initialize hub
var hub = $.connection.messageHub;
// hub.start();
$.connection.hub.start();
//Append event to Button
//hub.broadcast("c","b","a");
});
</script>
Now, after running it is get $.connection.messageHub as undefined
secondly my chrome network shows;-
Thirdly, when clicking on initiator for signalr/hub i get not implemented error:-
I have tried changing the URL's for scripts, also ran as IIS but couldn't get it working.
If i keep my scripts in .cshtml (View) and change --> use Local IIS Webserver, its working fine
Any help.!

Answer 1

#Scripts.Render("~/bundles/modernizr")
#Scripts.Render("~/bundles/jquery")
commented this section out in layout section and worked for me.

Answer 2

I found that adding reference to /signalr/hubs in bundle config dose not work because it is generated at run-time and bundling happens at compile-time.
so i did this:
1- created a section like this in each view i need to have reference to signalr/hubs:
#section SignalRScripts{
<script src="/signalr/hubs"></script>
}
2- in my layout file after rendering all other scripts, rendered this section:
#Scripts.Render("~/js")
#RenderSection("SignalRScripts", required: false)
#RenderSection("Scripts", required: false)
then it worked fine.
