AspectCastle

A lightweight AOP framework built on top of Castle DynamicProxy.

Introduction

Castle DynamicProxy provides a simple and easy way to write interceptors through the IInterceptor interface. However, it's quite cumbersome when you want to customize specific behaviors of the interception, specifically, the order of interception, and filtering on which methods to intercept. AspectCastle makes it very easy to accomplish both of these tasks.

Example

public class Foo {
    [WithMethodInvocation]
    public virtual void Bar1() { }
    
    public virtual void Bar2() { }
}

var f = new AspectCastle.ProxyFactory().CreateClassProxy<Foo>();
f.Bar1(); // this is intercepted with the MethodInvocationInterceptor
f.Bar2(); // this is not

Testing

All unit and integration tests pass using Castle.Core 3.1.0 (not the more recent 3.3.0). Additionally, the test runner will need to be ran as administrator for the performance counter tests to pass (i.e. launch Visual Studio as administrator if using Resharper, or launch the NUnit Console/GUI as administrator).
