    Sub FutureFunctionality()

    Sub Main()
        Try
            'This function is not implemented yet.
            FutureFunctionality()
        Catch ex As NotImplementedException
            Console.WriteLine("Exception: " & ex.Message)
        End Try
    End Sub
End Module

Explanation

In the above program, we created a module Module1 that contains two functions FutureFunctionality() and Main().

The FutureFunctionality() function throw NotImplementedException.

The Main() function is the entry point for the program. Here, we called the FutureFunctionality() function that will generate NotImplementedException that will be caught in the catch block and print an appropriate message on the console screen.
