I tried creating the executable going through the tutorials but i am not getting it right.

Could you please help in creating the skeleton.

Thanks in advance

推荐答案

此图与3层架构无关。 3层和EF是不一样的，但是你可以通过将所有EF代码放入数据层dll来实现。我个人认为这仍然是一个好主意，尤其是创建类的好主意，所以你的LINQ查询只能编写一次，而不是分散在你的代码中。



你如果你不知道怎么做，不应该从希望你做工作的雇主那里得到图表。

This diagram has nothing to do with a 3 tier architecture. 3 tier and EF are kind of at odds, but you can do it, by putting all your EF code in to a data layer dll. I personally think that it's still a good idea, and especially a good idea to create classes so your LINQ queries only get written once instead of scattered through your code.

You should not be getting diagrams from an employer who wants you to do work if you have no idea how to do it.
