Hello Alexander Sun,
The Telerik OpenAccess ORM domain model comes with build in validation framework. The framework is run to ensure the consistency of your Meta model. Having that in mind our validation framework considers the case where you have auto inc on a column that is not primary key as an error. This however is not a compile time error and you should be able to continue your work anyway. Be advised that any errors reported by the validation framework might cause runtime errors on a later stage.
Sincerely yours,
Petar
the Telerik team
