Whats wrong with this aspect

Question

I only want this invoked when a property is set. Why is this not working?

[DirtyTrackingAttribute(AttributeTargetElements =
   PostSharp.Extensibility.MulticastTargets.Property)]
class Program
{

    public static string Test { get; set; }

    static void Main(string[] args)
    {
        TestIt();
        Test = "foo";
        Console.ReadKey();
    }

    private static void TestIt()
    {
      Console.WriteLine("Real method called");
    }
}

[Serializable]
public class DirtyTrackingAttribute : OnMethodInvocationAspect
{
    public override void OnInvocation(MethodInvocationEventArgs eventArgs)
    {
        Console.WriteLine("Property invoked");
        eventArgs.Proceed();
    }
}

Answer 1

What exactly IS happening? Can you provide more information...an exception report if one exists, etc?

Answer 2

If you want the aspect to be applied on property setters only, you can filter the method name with the expression "set_*":

[DirtyTrackingAttribute(AttributeTargetMembers="set_*")]

PostSharp 1.* does not support explicitely properties; property accessors are considered as plain methods.
