'<membername>' is ambiguous across the inherited interfaces '<interfacename1>' and '<interfacename2>'

The interface inherits two or more members with the same name from multiple interfaces.

Error ID: BC30685

To correct this error

• Cast the value to the base interface that you want to use; for example:

  Interface Left
      Sub MySub()
  End Interface
  
  Interface Right
      Sub MySub()
  End Interface
  
  Interface LeftRight
      Inherits Left, Right
  End Interface
  
  Module test
      Sub Main()
          Dim x As LeftRight
          ' x.MySub()  'x is ambiguous.
          CType(x, Left).MySub() ' Cast to base type.
          CType(x, Right).MySub() ' Call the other base type.
      End Sub
  End Module
