Visual Studio 2013 中的 LightSwitch 有新增功能，包括更好的团队开发支持以及在构建 HTML 客户端桌面和 Office 365 应用程序方面的改进。本文结合最新发布的Wijmo 5提供的AngularJs进行图解。
基于Visual Studio LightSwitch作为数据源，我们使用Wijmo 5控件快速的创建 AngularJS应用程序。
插入数据记录
业务规则校验
数据记录更新
选择数据记录，点击键盘上删除按键
点击列头，进行数据排序
并发性校验（由LightSwitch的后端提供）。
2014年10月7日---葡萄城宣布正式发布Wijmo 5。Wijmo 5不再兼容传统浏览器（<= IE9），纯HTML5控件集。并且，发布并Wijmo 5全部的控件中将全面支持Angular JS。
例子如下所示：
在解决方案视图，在数据源DataSources右键，选择Add Table
创建ToDo表
点击写代码按钮，选择Validate方法，在生成的模板中，插入验证代码。
partial void ToDoes_Validate(ToDo entity, EntitySetValidationResultsBuilder results) { // Do not allow a task to be called {New Task] if (entity.TaskName == "[New Task]") { results.AddEntityError( "Task cannot be named [New Task]" ); } // Do not allow more than 1 incomplete Task if (entity.IsComplete == false) { int intCountOfIncomplete = this.DataWorkspace.ApplicationData.ToDoes .Where(x => x.IsComplete == false) .Where(x => x.Id != entity.Id).Count(); if (intCountOfIncomplete > 0) { results.AddEntityError( "Cannot have more than 1 incomplete Task" ); } } }
Wijmo 5下载地址：输入邮箱即可获得下载URL地址
解压Wijmo样例，定位到“..\Samples\JS\Angular\OData”目录，拷贝Vendor和styles文件夹到LightSwitch Server工程的Scripts文件夹。
创建wijmo.data文件夹，下载ODataCollectionView.js，并拷贝在wijmo.data文件夹下。
在scripts文件夹下创建app.js脚本文件，并输入如下代码。
// 在AngularJS 声明依赖 Wijmo "wj" module: var app = angular.module(‘app‘, [‘wj‘]);
‘use strict‘; var app = angular.module(‘app‘); app.controller(‘appToDoCtrl‘, function appToDoCtrl($scope) { // define data service URL and data types for specific columns var oDataService = ‘/ApplicationData.svc‘, dataTypes = []; // load ToDos table $scope.cvToDo = new wijmo.data.ODataCollectionView( { serviceUrl: oDataService, entityName: ‘ToDoes‘ }, [‘Id‘], { serverSettings: { selects: [‘Id‘, ‘RowVersion‘, ‘TaskName‘, ‘IsComplete‘, ‘Created‘, ‘Modified‘] } }, dataTypes, loaded, true); // Display any errors $scope.cvToDo.error.addHandler(function (sender, args) { alert(sender.errorMsg); }); // tell scope when tables finish loading function loaded() { $scope.$apply(); } });
创建ToDo.htm页面，并输入如下代码：
<!DOCTYPE html>
<html lang="en" ng-app="app" ng-controller="appToDoCtrl">
<head>
<meta charset="utf-8" />
<title>To DO</title>
<!-- ensure IE uses the latest version of IE (yes, yes...) -->
