A couple of years ago I posted an article demonstrating how Castle DynamicProxy and Castle Windsor can be used to implement concepts of Aspect-Oriented Programming (AOP). The version of Castle that I used at the time was even then an old out of date version. So I thought I'd revisit that little project and bring it up to date using the current latest versions of Castle.Core (contains DynamicProxy) and Castle.Windsor.
This article is a short demonstration of using Castle DynamicProxy for a somewhat real world application of Aspect-Oriented Programming (AOP). For the sake of this example, imagine, if you will, that you need to count some beans. But not just a few beans, no indeed, you need to count boxes and boxes of beans. For this important task what you need is a dedicated Bean Counter.
You probably already know this, but there is a difference between the logical operators (| and &) and the conditional logical operators (|| and &&). The difference is conditional logical operators short circuit but the logical operators do not.
Many .NET framework types, particularly from earlier versions of .NET, aren't implemented in a way that makes the type easy to construct or mock in tests. The same can be said for many third-party libraries that your (legacy) applications may be dependent on upon. To a certain extent this also could apply to your (legacy) code, which in theory could be modified but large changes may be too risky in the time available. For this post I will focus on one particular type that often is the cause of much pain when trying to get code under test, namely System.Data.DataRow
