CallerMemberNameAttribute and .Net 4
<p>All,</p>

<p>I noticed in .Net 4.5 there is a CallerMemberName attribute, which Blend specifically uses to raise a PropertyChanged event from the calling method.  My question is, since this attribute doesn't specifically exist in .Net 4.0, is it possible to somehow duplicate this behavior by creating a custom attribute?  Code samples much appreciated.</p>
