POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObjectfunctionalities like
POCO（普通的旧 CLR 对象）只是域的实体。通常，当我们使用实体框架时，实体会自动为您生成。这很好，但不幸的是，这些实体散布着数据库访问功能，这显然违反了 SOC（关注分离）。POCO 是没有任何数据访问功能的简单实体，但仍提供所有EntityObject功能，如
- Lazy loading
- Change tracking
- 延迟加载
- 变更追踪
Here is a good start for this
这是一个好的开始
You can also generate POCOs so easily from your existing Entity framework project using Code generators.
您还可以使用代码生成器从现有的实体框架项目轻松生成 POCO。
