Review

When would you reference a resource dynamically instead of statically?

What markup extension must you add to an element declaration inside a ResourceDictionary?

In order to make the dictionaries available to the entire application, the ResourceDictionary.MergedDictionaries collection is usually defined inside what file?

What property do you declare to base one property on another?

How do you create an implicit style?

Textboxes that contain required information should be red and italic when they’re not selected, pink when they’re not enabled, and bold when they are focused and CanUndo is true. Write the style.
