Repository Caching with Aspect Oriented Programming

Repository Caching with Aspect Oriented ProgrammingThis post provides a walkthrough of how to implement basic cache handling at the repository layer using Aspect Oriented Programming (AOP). I’ve chosen PostSharp’s AOP framework and built a relatively simple Domain-Driven Design (DDD) solution in .NET to illustrate how it all ties together.

I want delve into too much AOP detail up front other than to reiterate the usual AOP pitch – that it’s an incredibly useful programming paradigm which addresses cross-cutting coding concerns within application development. What does that mean in English? Once you’ve mastered the basic AOP terminology and implementation requirements you can use it to remove a lot of duplicate code that appears throughout your solution. If you’re not familiar with AOP then take a quick moment to watch one of PostSharp’s many introductory screencasts or browse through their documentation. Keep in mind that AOP isn’t OOP as you work your way through the following code, it complements OOP extremely well but doesn’t follow object-oriented principles. Continue reading
