The Meta Model Contains More Than One Persistent Type With Name

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 more than one persistent type with the same name.


To resolve this error, rename one of the domain classes:

  1. Select one of the types with duplicated name in the Visual Designer.
  2. Press F4 to open the Properties pane.
  3. Set a unique name for the type.
