使用实体框架实体作为业务对象？ [英] Using Entity Framework entities as business objects?

问题描述

我正在使用Microsoft的Entity Framework O / R映射器，并将实体类（映射到DB对象的生成类）用作业务对象。
这样可以吗？请说明你的利弊。在业务层和演示文稿之间进行WCF通信的情况下如何处理，如何将这些对象作为数据成员发送？

解决方案

我以这种方式使用EF，一个很好的功能是生成的实体是部分类，允许它们以相当的方式被扩展，以免再生问题。

另外请查看 MSDN上的此链接，其中介绍了一些常见的使用场景EF关于业务逻辑。

I'm using Entity Framework O/R mapper from Microsoft and using entity classes (generated classes that are mapped to DB objects) as a business objects. Is this OK? Please state your cons or pros. What to do in a case of WCF communication between business layer and presentation, how to send those objects as data members?

解决方案

I am using EF in this fashion and one nice feature is that generated entities are partial classes, allowing them to be extended in a way that is fairly protected from regeneration issues.

Also take a look at this link on MSDN which describes some common usage scenarios with EF in regards to Business Logic.
