WF随笔系列之三 Out-of-the-Box Activities 专题目录
3.1 什么是Activities？
Activities是工作流是核心，如果没有行为，就是没有workflow了, 或者说workflow由于一堆行为组成。
Activities包括activity，composite activity ;那一个activity能执行一个单个动作，如写一个值到数据库；composite activity就是由一组activity组成的。
Activities有两种行为类型：runtime和design time。
- 运行时行为在执行时指定具体的动作
- 设计时可以在设计器里面调整activity的外观和它们的交互.
