Are routed events weak in WPF

Question

Does routed events in WPF store strong reference to the handler that is attached to them?

Answer 1

If the control author implemented the WeakEvent pattern then yes. I believe the stock controls use this pattern.

UPDATE: They in fact do NOT. Here is a reference on this and other potential performance problems:
