SignalR Type Error

I'm using signalR in my project. But I 'm getting this error

'Uncaught TypeError: Cannot read property 'client' of undefined'

my Code is

var notification = $.connection.CounterHubs;

notification.client.inboxMessageCount = function (c) {
    ViewModel.InboxMessages(c);
}

thanks for answer

This tends to happen when you haven't included the automatically generated hubs file into your page.

Include the hubs file into your page:

<script src="http://example.com/signalr/hubs"></script>

If you have included it already, open your developer tools (F12) and check the value of $.connection.CounterHubs; in your code and verify that it is not 'undefined'.

I guess it is because your hub is written with an Uppercase.

From the documentation:

In JavaScript the reference to the server class and its members is in camel case. The code sample references the C# ChatHub class in JavaScript as chatHub.

So it should probably be:

var notification = $.connection.counterHubs;

See this page on getting Started with SignalR:
