The Base Type Identity Member Is Not Visible In The Derived Types
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 base type identity is not visible in the derived types, e.g. the access modifier for the identity property is private.
Solution
To resolve this error, change access modifier so that the identity member is visible in the derived classes:
- In the Visual Designer, select the identity property of the base type.
- Press F4 to open the Properties pane.
-
Change the Access Modifier property.
