SignalR demo not working

Question

I'm following this quick tutorial on getting a SignalR project started, and in my Hub class, I have the following

using Microsoft.AspNet.SignalR.Hubs;

namespace MvcApplication8.Hubs
{
    public class ChatHub : Hub
    {
        public void BroadcastMessage(string message)
        {
            Clients.writeMessage(message);
        }
    }
}

Client code:

    $(document).ready(function () {
        var chat = $.connection.chatHub;
        chat.writeMessage = function(msg) {
            $("#messages").append("<li>" + msg + "</li>");
        };
        $("#buttonSubmit").click(function () {
            chat.broadcastMessage($("#txtInput").val());
        });
        $.connection.hub.start();
    }); 

However I'm getting a compile time error saying:

'Microsoft.AspNet.SignalR.Hubs.HubConnectionContext' does not contain a definition for 'writeMessage' and no extension method 'writeMessage' accepting a first argument of type 'Microsoft.AspNet.SignalR.Hubs.HubConnectionContext' could be found (are you missing a using directive or an assembly reference?)

Where went wrong?

I installed SignalR into my project from http://nuget.org/packages/microsoft.aspnet.signalr using the package manager console "Install-Package Microsoft.AspNet.SignalR -Pre"

Did you create the corresponding client-function?

<script type="text/javascript">
    $(function () {
        var chat = $.connection.chat;
        chat.writeMessage = function (message) {
            $('#messages').append('<li>' + message + '</li>');
        };
        $.connection.hub.start();
    });
</script>
