Reference required to assembly '<assemblyname>' containing the implemented interface '<interfacename>'
Reference required to assembly '<assemblyname>' containing the implemented interface '<interfacename>'. Add one to your project.
The interface 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 interface is defined in more than one DLL or assembly.
Error ID: BC30009
