Aspect Oriented Programming in C# [closed]

Question

Are there any good resources to wrap my head around Aspect Oriented Programming?

PS: I need to understand AO programming, not the libraries or frameworks available for .NET or C# :)

Answer 1

Just to get your head around it: It is the ability to hook events such as: creation of objects, setting of properties, etc, and attach general functions to them, that will be populated with relevant context.

Because C# doesn't have an inbuilt facility for this, you need a framework, like PostSharp, to do 'bytecode weaving' (i.e. just writing code to actually make the calls, directly to your classes) to simulate it.

Answer 2

Aspect Oriented Programming means having a meta level where yo can define logging or security/access control features to interweave with your code instead of implementing these feature very time in your code. So instead of beeing one-dimensional, you have to program two-dimensional.

I know this may sound very esotheric but it is easy once you understood it.

AOP often works with proxy classes which intercept calls and do things in the background.

Answer 3

What a timely question?

Here is the podcast worth listening.
This will give you a good overview on what is AOP? where it can be used?

Hope that helps.

Answer 4

A good link below, shows you how to code up an AOP framework of your own. Unfortunately, all of your consuming classes have to inherit from the MarshalByRefObject (through ContextBoundObject).

Answer 5

check this out, it is describing how to implement AOP ( log, timing, tracing, exception handling...) using postsharp
