When overridden in a derived class, is invoked whenever application code or internal processes (such as a rebuilding layout pass) call ApplyTemplate.

This method has no default implementation.
Derived classes can use this method as a notification to:
Builds the remainder of an element visual tree using custom code.
Run code that relies on the visual tree from templates having been applied, such as obtaining references to named elements that came from a template.
Introduce services that only make sense to exist after the visual tree from templates is complete.
Set states and properties of elements within the template that are dependent on other factors. For instance, property values might only be discoverable by knowing the parent element, or when a specific derived class uses a common template.
