UIElement vs FrameworkElement

Question

I am unclear about when you would use a UIElement as opposed to a FrameworkElement, and why is there a FrameworkElement class at at all. Essentially, what is the extra functionality that a FrameworkElement provides as opposed to UIElement?

Answer 1

You should never inherit from UIElement (no class besides FrameworkElement does), among other properties it has no DataContext, whose lack can land you in some troubles.
