Cannot show interface because '<element>' cannot be found

Class Designer generates this error when the declaration of an interface is invalid or missing in the source code.

To correct this error

  • Ensure that the code element that you entered is an existing interface.

  • If the code element that you entered is defined outside your project, ensure that you have included the correct references in Solution Explorer.

  • If you modify your project structure or move source files in the project, Class Designer can lose track of the type. (This is especially true of the source type of a typedef, base classes, or association types.) If this is the case, drag the modified or relocated source code to the class diagram again to redisplay it.
