Or may be there are some practices/patterns?
thanks in advance.

1) Create table to store last id (int, bigint) (identifier domain)
2) Add stored procedure to retrieve the next id (int, bigint).
3) You may implement Custom Data Class EntityObject and ComplexObject (or maybe assign to every entity manualy in code)
4) Use this id in your custom class as primary key

If you using GUID…EF(4) has build-in feature to do this. But GUID as primary key with CLUSTERED INDEX is bad solution for the many insertion of course.
