'<interfacename>.<membername>' is already implemented by the base class '<baseclassname>'. Re-implementation of <type> assumed

A property, procedure, or event in a derived class uses an Implements clause specifying an interface member that is already implemented in the base class.

A derived class can reimplement an interface member that is implemented by its base class. This is not the same as overriding the base class implementation. For more information, see Implements Clause (Visual Basic).

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

Error ID: BC42015

To correct this error

  • If you intend to reimplement the interface member, you do not need to take any action. Code in your derived class accesses the reimplemented member unless you use the MyBase keyword to access the base class implementation.

  • If you do not intend to reimplement the interface member, remove the Implements clause from the property, procedure, or event declaration.
