The Source Class Of The 1:1 Association Uses Backend Calculated Identity

This article is relevant to entity models that utilize the deprecated Visual Studio integration of Telerik Data Access. The current documentation of the Data Access framework is available here.

This error occurs when the domain model contains an one-to-one association where the source class uses the DatabaseServerCalculated identity mechanism.


To resolve this error, either manually delete the association in the designer or change the identity mechanism for the source class.

To change the identity mechanism:

  1. Double-click the error to open the Validation Dialog.
  2. Specify a different identity mechanism.
