In the previous article we've seen how an attached property can come in handy on adding validation logic to an input control. This time around I'll be using a MarkupExtension that is somewhat similar to the Binding class we're all used to, but extends it to accommodate our own validation. There are lots of important WPF concepts in this article too, you shouldn't miss it.
