I created edmx file by unchecking the option for creating entites for foreign keys.So there is no mapping for my foreign key fields. Is it possible to map foreign keys without creating a new edmx file ? If possible How.? I created .edmx from a database which I had already.I am using VS 2012 .Thanks .
答
右键单击EDMX，从数据库中击中更新模型。还有的在那里外键的复选框。这就是你要找的是什么？
Right click in the edmx, hit update model from database. There's a checkbox for foreign keys in there. Is that what you're looking for?
