Class Designer errors

Applies to: Visual Studio

This article introduces how to resolve Class Designer issues in Visual Studio.

Symptoms

After you modify the source type of a typedef, base classes, or association types, you might receive the following error:

Class Designer is unable to display this type.

Cause

Class Designer does not track the location of your source files, so modifying your project structure or moving source files in the project can cause Class Designer to lose track of the type.

Resolution

To resolve the error, drag the modified or relocated source code to the class diagram again to display it.
