在实践本示例之前，你需要已经：
1. 有Azure账号
2. 已经创建了Service bus
3. 有权限部署到Cloud
1. 创建Azure Cloud Service 项目
2. 选择1个WebRole
3. 创建一个Hubs文件夹和ChatHub.cs：
public void Send(string name, string message)
{
Clients.All.broadcastMessage(name, message, Environment.MachineName, RoleEnvironment.CurrentRoleInstance.Id);
}
4. 安装所需要的nuget:
microsoft asp.net signalR
signalR service bus
5.打开Home/Index.cshtml
添加如下代码（注意你的jquery和signalR版本，做相应替换）：
@{
Layout = null;
}
<html>
<head>
<link rel="shortcut icon" href="http://icons.iconarchive.com/icons/sora-meliae/matrilineare/96/Status-dialog-information-icon.png">
<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src="~/Scripts/jquery.signalR-2.2.0.js"></script>
<script src="/signalr/hubs"></script>
</head>
<body>
<div class="container">
<input type="text" id="message" />
<input type="button" id="sendmessage" value="Send" />
<input type="hidden" id="displayname" />
<ul id="discussion"></ul>
</div>
<script type="text/javascript">
$(function () {
var newMsg = false;
var window_focused = false;
var chat = $.connection.chatHub;
chat.client.broadcastMessage = function (name, message, machineName, instanceId) {
newMsg = true;
var encodedName = $(‘<div />‘).text(name).html();
var encodedMsg = $(‘<div />‘).text(message).html();
$(‘#discussion‘).append(‘<li><strong>‘ + encodedName + ‘</strong>: ‘ + encodedMsg );
};
var name = prompt(‘Enter your name:‘, ‘‘);
$(‘#displayname‘).val(name);
$("#discussion").append("<li><strong>" + name + " entered" + " room </strong></li>");
$(‘#message‘).focus();
$("#message").keydown(function(e) {
if (e.keyCode === 13) {
$(‘#sendmessage‘).click();
}
});
function setTitle1() {
if (newMsg === true) {
document.title = "New Msg";
setTimeout(setTitle2, 500);
}
}
function setTitle2() {
if (newMsg === true) {
document.title = "";
setTimeout(setTitle1, 500);
}
}
setInterval(function() {
if (window_focused === false) {
setTitle1();
}
}, 1000);
$.connection.hub.start().done(function () {
$(‘#sendmessage‘).click(function () {
newMsg = false;
chat.server.send($(‘#displayname‘).val(), $(‘#message‘).val());
$(‘#message‘).val(‘‘).focus();
});
});
$(window).focus(function (e) {
newMsg = false;
window_focused = true;
});
});
</script>
</body>
</html>
6. 打开Web.config，把ServiceBus的连接串放在AppSetting中：
<add key="ServiceBusConnectionString" value="Endpoint=sb://your string/;SharedAccessKeyName=your key;SharedAccessKey=your key" /></appSettings>
7. 打开App_Star/Starup.Auth.cs
添加如下代码：
GlobalHost.DependencyResolver.UseServiceBus(
CloudConfigurationManager.GetSetting("ServiceBusConnectionString"), "MyChat");
app.MapSignalR();
8. Publish你的AzureCloudService到Azure。
