} } }

<script src="signalr/hubs"></script> 
<script type="text/javascript"> 
$(function () { 
// Declare a proxy to reference the hub. 
var chat = $.connection.chatHub; 
// Create a function that the hub can call to broadcast messages. chat.client.broadcastMessage = function (name, message) { 
// Html encode display name and message. 
var encodedName = $('').text(name).html();
var encodedMsg = $('').text(message).html(); 
// Add the message to the page. 
$('#discussion').append('' + encodedName + ':  ' + encodedMsg + ''); }; 
// 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.

$('#message').val('').focus(); 
}); }); });

Hi colotoon,

signalr/hubs 404 not found

Please check ASP.NET SignalR FAQ "Why does signalr/hubs return 404 or Why do I get 'myhub' is undefined?".

https://github.com/SignalR/SignalR/wiki/Faq#why-does-signalrhubs-return-404-or-why-do-i-get-myhub-is-undefined

Besides, if possible, please share a reproducible sample, so that we can test and troubleshoot the issue based on it.

With Regards,

Fei Han

Hello

1st of all u need understand easy thing: many ppl dont know asp.net, aspacialy IIS server(all uses Apache and PHP), so, u need make "how to start" maximaly informed about all!

I used to get a working solution out of the box, in this case its working at VS but not working as published in IIS - its ur fault!

U give link to wiki, ok, why i need goto wiki if im using "how to start" manual, mmm?? sry but its stupidness...

So, show me plz, at siglanR manual guide, where need to put:

RouteTable.Routes.MapHubs();

to my code? mmm?? ofcouse i cant, its not exist, but need to app this thing to guide.

or where i can see at manual this:

If the above still doesn't work, make sure you have RAMMFAR set in your web.config:

<configuration>
   <system.webServer>
        <modules runAllManagedModulesForAllRequests="true">
        </modules>
    </system.webServer>
</configuration>

mmm? no where... so sad...

</div>



Next, as i told, this is not works:

<script type="text/javascript" src="~/signalr/hubs"></script>

<script type="text/javascript" src="@Url.Content("~/signalr/hubs")"></script>

<script type="text/javascript" src='<%= ResolveClientUrl("~/signalr/hubs") %>'></script>

U ask me full code, ok, look here:
https://docs.microsoft.com/en-us/aspnet/signalr/overview/getting-started/tutorial-getting-started-with-signalr

try to follow this guide and build app, then publish it to IIS and u will see - its not working, so u guys need to fix "how to start" page!

How i fix it? I just use self-host technics, only this is working for me, and im happy now, 
i not need to use this (#@#%) IIS and ASP tags (thanks Gods!)

And 1 more thing, this published app dont working and in apache too.

So, what u can to do - plz fix starting guide + sample code to 100% working code, ppl not need working only in VS, ppl need pubish apps,
so plz make it working, ok?

And TY for answer.
Have a nice day.
