VB.NET Core Classes in a Nutshell

Name

NotImplementedException

Synopsis

This exception signals an attempt to access an unimplemented method or operation.

Suppose you have a base class with a number of unimplemented methods. You may have reason not to mark them as MustInherit (perhaps you want to let programmers develop subclasses that only implement some of the base class methods). You can throw this exception in those methods, letting users of the subclass know that they are not implemented.
