'Microsoft.VisualBasic.ComClassAttribute' is specified for class '<classname>' but it has no public members that can be exposed to COM; therefore no COM interfaces are generated

A class using a COMClassAttribute attribute block does not define any Public properties or methods. If a class is to be exposed as a COM object, its properties and methods must be declared with Public access.

The message is a warning by default. For more information on hiding warnings or treating warnings as errors, see Configuring Warnings in Visual Basic.

Error ID: BC40011

To correct this error

• Add the Public keyword to one or more properties or methods in the class, or remove the COMClassAttribute attribute block.
