c# - SignalR 演示不工作

Question

我正在学习这个关于启动 SignalR 项目的快速教程，在我的 Hub 类中，我有以下内容

using Microsoft.AspNet.SignalR.Hubs;

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

客户端代码:

    $(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();
    }); 

但是我收到一个编译时错误:

'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?)

哪里出了问题？

我从 http://nuget.org/packages/microsoft.aspnet.signalr 将 SignalR 安装到我的项目中使用包管理器控制台“Install-Package Microsoft.AspNet.SignalR -Pre”

您是否创建了相应的客户端功能？

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