问题描述

如何将引用bll引用添加到数据访问层

how to add reference bll reference to the data access layer

推荐答案

当您有两个或更多使用另一个的组装项目时，您将获得循环引用：因此，遵循引用链将导致无限循环。

解决此问题的最佳方法是创建包含常用材料的第三个程序集，但不需要引用任何其他程序集，以及让两个项目都参考。

You get a circular reference when you have two or more assembly projects that each use the other: so following the reference chain will cause an infinite loop.
The best way to resolve this is to create a third assembly which contains the "common" materials, but does not need to reference any other assemblies, and have both projects refer to that instead.
