etc.

Anything else?

I tested the sample because we had a every strange behavior in our app regarding tinting on windows: when the tint color is directly bound to our observable property the color is not applied, but when we chain-bind the property it works. Below is an example of what I would call chain-binding: we bind the color to a label instead of binding directly to the tint color and then we bind the tint color to the label's property...,, and it works....

P.S. "Context" is a property is in our model (it is not static in case someone wonders)
