Using advices

As an attribute

Usually, you will just set the attributes to target method or property

[ADummyPropertyAdvice]
public int AnAdvisedProperty { get; set; }

[ADummyMethodAdvice]
public void MethodTest()
{
}

to target a type set the attribute at type level

[ADummyTypeAdvice]
public class SomeClass
{
   ...
}

to target all types in an assembly set the attribute at assembly level

using System;

[assembly: ADummyAdvice]

namespace SomeNameSpace
{
    public class SomeClass
    {
        ...
    }
}

Advise an external interface

You can also intercept all calls to a given interface, even if it is external to your code. There is a special extension method named Handle<TInterface>() which applies to advices.

public class ADummyAdvice: Attribute, IMethodAdvice
{
    public void Advise(MethodAdviceContext context)
    {
        // DO what you want, but...
        // DON'T call context.Proceed(), because there is no implementation
    }
}

public void DoSomethingWithIt()
{
    var advice = new ADummyAdvice();
    ISomeInterface advisedInterface = a.Handle<ISomeInterface>(); 
    // all calls to advisedInterface will go through the ADummyAdvice, and you'd better intercept them.
}
