.net - How to find an identity of the last inserted row in Entity Framework?

Question

I am inserting data in multiple tables. I need to know the last inserted (auto-incremented) ID in the table. I need to use it as a Foriegn Key in some other table.

In short I need alternative of @@Identity in T-Sql.

Answer 1

Entity Framework will automatically load the last inserted id to populate the primary key column of the inserted entity:

var customer = new Customer { Name = "Steven" };

context.AddObject(customer);

context.SaveChanges();

var id = customer.Id;

Note that the Id property only gets populated after calling SaveChanges() in case the StoreGeneratedPattern attribute is set to "Identity" or "Computed" for the auto-incremented ID column in the Storage part of the model.
