应用 XAF 开发移动手机应用：
1、 How to create a native mobile or lightweight web client UI based on the existing XAF application database, data model and logic?
2、客户端 Decide what you would use for the client UI part, e.g. DevExtreme, Xamarin, DataExplorer or other tools.
For instance, the documentation for creating and customizing mobile apps with DevExtreme is available here: http://js.devexpress.com/Documentation/Overview/

4、Q: How is the backend application service built?
A: The new XAF mobile application project automatically created from the XAF Solution Wizard in Visual Studio contains three main classes:
1. YourSolutionNameDataServiceMobileApplication (MobileApplication.cs) - this class derives from the new MobileApplication class similarly to WinApplication or WebApplication in appropriate platforms. An instance of YourSolutionNameDataServiceMobileApplication is created for each request from the client application.
2. DataService (DataService.svc) - this is the backend service for mobile applications used to serve requests, manage security and execute actions. Technically, it is a regular OData service (WCF Data Services 5.0) based on XPO OData V3 provider , XPO being the only currently supported ORM (Entity Framework support is coming later).
3. MetadataService (MetadataService.svc) - this service supplies mobile application configuration data to a separate device simulator service.
4. Simulator (Index.html and player.html) - technically this is a web page that contains a client "player" script that queries the aforementioned backend data and UI metadata services and generates the actual HTML5/JS UI inside the web browser. This player script also gets redistributed to the actual mobile device when a native package is installed. The simulator is automatically opened in the web browser when you make a YourSolutionName.Mobile project as startup in Solution Explorer and start debugging (F5). Note that currently this simulator downloads some resources from Azure and thus requires Internet connection.
NOTE: Starting with v16.1.6+, the Simulator files were removed from the mobile project. All the resources are obtained from an assembly automatically and there is also an HTTP handler that handles a virtual URL like http://localhost:51985/Static/16.1.6.0/Index.html in the web browser.
