AOP - Injection Code

Hi all,We have an application that needs to log all the methods executed, but writing the same code on all the methods wouldnt be nice, so we thought about using AOP on it. I tried to find some articles on web about frameworks, comparing them etc, but i hadnt much success, cuz the articles was too old or too simple.Does anyone here uses a framework for AOP? Which one is the best one? Aspect.NET, Aspect.C#, Spring.NET + Loc, Enterprise Library?If you have an article comparing AOP Frameworks would help me a lot too.Regards, ...
