Reference required to assembly '<assemblyname>' containing the base class '<classname>'

Reference required to assembly '<assemblyname>' containing the base class '<classname>'. Add one to your project.

The class is defined in a dynamic-link library (DLL) or assembly that is not directly referenced in your project. The Visual Basic compiler requires a reference to avoid ambiguity in case the class is defined in more than one DLL or assembly.

Error ID: BC30007

To correct this error

  • Include the name of the unreferenced DLL or assembly in your project references.
