Comparación de uso del patrón de diseño decorator y la programación orientada a aspectos en .NET para modularizar incumbencias cruzadas

Abstract

Looking for modular .NET software solutions, this article describes and illustrates how to produce modular .NET solutions through the use of the object-oriented software design pattern Decorator and the aspectoriented programming (AOP) tool PostSharp for the crosscutting concerns modularization of an application. The application is a base and traditional crosscutting concerns example (logging example). This article presents solutions of logging by the use of Decorator and PostSharp for the modularization of its crosscutting concerns. It also gives details of the advantages and disadvantages of both solutions. Furthermore, this article specifies AOP information that is part of PostSharp and proposes applying PostSharp and Decorator to achieve higher modularity level solutions.
