'Microsoft.VisualBasic.ComClassAttribute' cannot be applied to '<classname1>' because its container '<classname2>' is not declared 'Public'

  • Article

A class using a COMClassAttribute attribute block is declared inside a class that is not Public. If a class is to be exposed as a COM object, its entire containment hierarchy must be declared with Public access.

Error ID: BC32504

To correct this error

  • Declare all containing classes Public, or remove the COMClassAttribute attribute block.
