T4模板基础就不在这里重复了，园子里有很多文章讲解T4模板。
今天给大家介绍一个实例 主要是针对WPF MVVM中Model的书写，
Model的格式大致是：
// 测试private string a;/// <summary>/// 测试/// <summary>public string A{get{return a;}set{if (a != value){a = value;this.RaisePropertyChanged("A");}}}在Model 类中一般都是重复性质的工作，，所有选择T4来生成该文件是个不错的选择。
生成model的核心代码如下：
BaseModelT4.tt
