Method Deactivate and TryClose - Caliburn.Micro

I would be very grateful if someone explain my "differences" between method Deactivate and TryClose in MVVM framework Caliburn.Micro.

For example my app has this structure:

• Shell (WPF window)
  • SomeScreen (User control) - is active

I know that method is Deactivate is call everytime if is screen deactivated. An method TryClose is used on attempt to close some screen.

My questions are:

1. I click on X button on WPF window. First is call method deactivate on SomeScreen object and then is call the same method on Shell object ?

   After deactivate开发者_开发知识库 method is totally object destroyed? - "remove reference on him"?

2. When I close WPF window which is shell it call wich methods from IConductor ?

This has been changed in a recent update to Caliburn Micro.

There's just the Deactivate method now that can optionally take a bool to say whether it is closing or not.
