XML serialization can't update an existing object, it always creates a new one when you deserialize. Since it's a new object, there isn't any handler for PropertyChanged yet, so the event isn't fired.
I totally agree with Thomas's answer and add a few suggestions.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
