"Mouse Recorder" desde .NET

Una manera eficiente de capturar el recorrido de un mouse para luego implementarlo al estilo"Robot" ésta colaboración es de ElecKtro H@cker;

Captura/Guarda cada coordenada en una lista de punteros.
Captura/Guarda cada click en un tipo de diccionario.
Luego, reproduce el contenido de la lista y del diccionario.
Aquí el code para .NET 2012 

Public Class Form1

Hay otras formas de realizarlo pero a mi criterio esta es mas eficiente que las otras que vi.

Saludos.
