在of clientServiceHelper.js文件部分，我們使用了一個ASP.NET AJAX
客戶端對象模型來編寫JavaScript客戶端代碼。
Type.registerNamespace("ServiceClients");
ServiceClients.ToDoClient = function() {
}
ServiceClients.ToDoClient.prototype = {
AddToDo: function(todo, callback, errorCallBack) {
ServiceLibrary.IToDoService.AddToDo(todo, callback, errorCallBack);
},
DeleteToDo: function(todo, callback, errorCallBack) {
ServiceLibrary.IToDoService.DeleteToDo(todo, callback, errorCallBack);
},
UpdateToDo: function(todo, callback, errorCallBack) {
ServiceLibrary.IToDoService.UpdateToDo(todo, callback, errorCallBack);
},
GetAllToDo: function(callback, errorCallBack) {
ServiceLibrary.IToDoService.GetAllToDo(callback, errorCallBack);
},
dispose: function() {
}
}
ServiceClients.ToDoClient.registerClass('ServiceClients.ToDoClient', null, Sys.IDisposable)
if (typeof (Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();

ScriptManager manager = ScriptManager.GetCurrent(Page);
ServiceReference reference = new ServiceReference("ToDoService.svc");
manager.Services.Add(reference);
