If Ling to Entity, please share with me little tutorial about how to do this in asp.net mvc. or give some advices.

Answer 1

You could have a look at the NerdDinner tutorial at scottgu's site. It is a very basic application using LINQ to SQL. The read is quite good though and while I have never really used it (i am using ADO.net entities) I did learn quickly how to use ASP.net MVC.

So for a good read:

Answer 2

如果仅在两个表之间创建FK关系，则EF会自动创建它们之间的关联，并在您要求他这样做时自动进行联接。

Answer 3

I'd recommend taking a look at Rob Conery's series on Commerce MVC (or just grab the code and check out his implementation). It has a nice clean data layer and has support for lazy loading.
