entity framework - Get Auto Identity Key after Insert via EF

Question

Is there a straight forward way of retrieving a DB auto generated primary key when adding a record via Entity Framework 4.1?

For example:

dbcontext.Entity_Tables.Add(new Entity_Table { item1 = val1, item2 = val2 });
dbcontext.SaveChanges();
newPK = ???;

The SQL equivalent would be:

newPK = executeOnDB("INSERT INTO Entity_Table (item1, item2) VALUES (val1, val2);SELECT @@Indentity";);

BTW I'm using MySQL but the SQL would be the same as on MSSQL

I believe EF should update your entity object with the identity:

var entity = new Entity_Table { item1 = val1, item2 = val2 };
dbcontext.Entity_Tables.Add(entity);
dbcontext.SaveChanges();
int newPK = entity.ID;
