WCF项目的架构设计
本文将介绍以WCF开发项目为主的架构设计，主要从类库的分类和代码的结构。
下面将以一个WCF实例做具体的介绍。此项目底层是一个Windows Service，WCF服务Hosted在此Windows Service上，WCF向外暴露REST接口供第三方调用，仅为单向通讯。
项目的目录结构如下图：
项目介绍：
***CentralService：
Windows service 项目，它是一个windows service的壳，同时定义关于此服务的权限、介绍、名称等内容，里面会调用OnStart和OnStop事件，分别关联Windows服务的启动和停止事件。具体的工作在下面的***StartEngine项目中，之所以分离开有以下两方面原因：
1.为方便调试，除在Windows服务中可以启动整个程序，一般会新建一个Console程序启动整个程序以便调试，所以启动程序最好是一个操作单元（unit，即***StartEngine项目）
2.OnStart和OnStop默认有一个超时时间（timeout），所以在启动服务时为了避免不超时一般采用另起一个新线程启动整个程序，单独做一个操作单元会很方便新线程调用

***WCFRestContract：
WCF服务的接口项目，包含如下内容以方便其他项目调用本项目的主要功能是：
1.定义WCF服务的接口
2.整个程序中用到的公共实体（Entity）
3.整个程序中用到的公共方法

}
***WcfRestService：
WCF服务的具体实现，真正服务的实现和处理都在这个项目中。
本项目的所有方法一般只是个壳，具体的业务实现需调用***CentralServiceCore，目的是保证整个项目的稳定。
为了项目的稳定（windows service或client程序），在这里的每个方法都要做try catch，捕获所有从底层服务或本方法抛出的异常。
一般底层服务不再需要try catch异常，因为会一直抛到最上层被这个项目给抓住，多线程调用的底层方法需自己捕获并处理异常。
主要功能如下：
1.catch住整个程序的所有异常
2.记录异常等日志信息
3.记录方法调用日志信息

***CentralServiceCore：
这个项目是具体的业务实现，***WcfRestService中的服务一般调用***CentralServiceCore里的方法，以方便处理异常。本项目的内容一般不需捕获异常，出了问题直接抛给了***WcfRestService，复杂的逻辑一般在这里处理。多线程的调用需要在这里做异常处理。
