In a prior blog post I had created a Blend Behavior for creating a bindable ApplicationBar. The problem with the Blend Behavior is it seems to have a static instance that then attaches to multiple objects. It’s very confusing to me and I need to do a lot more research on Blend Behaviors. The result has been the creation of a BindableApplicationBar attached property.
