When a Version Concurrency Control Strategy Is Used There Must Be a Version Field For The Persistent Type

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 a persistent class that uses the Version concurrency control but a concurrency member (version field) is not specified.


To resolve this error, specify a concurrency member (version field):

  1. Select the persistent class in the Visual Designer.
  2. Press F4 to open the Properties pane.
  3. Specify a concurrency member.
