public override sealed bool Equals(

true if the two instances are the same; otherwise, false.

This implementation is reference equality only, and does not attempt to evaluate value equality of the contained properties.

Notes to Inheritors

DependencyObject overrides and then seals two basic Object methods: Equals and GetHashCode. The overrides call the Object implementations, resulting in an object equality behavior. The purpose of these deliberate overrides is to prevent derived classes from trying to define a value equality for a DependencyObject. Value equalities for DependencyObject will never be accurate because of the innate property value-changing capabilities of a DependencyObject and its dependency properties. This includes fundamental WPF features such as data binding and the WPF property system.
