What's the difference between x:Key and x:Name in WPF?

Question

What\'s the difference between x:Key and x:Name in WPF?

I am not sure what the true difference is.

Answer 1

x:Key is only valid in the scope of a ResourceDictionary element. x:Key is used as the primary identifier for elements in the ResourceDictionary.

On the other hand, x:Name is valid in the scope of everything but a ResourceDictionary. x:Key is not valid outside the ResourceDictionary scope.
