Looks like you are binding your ListBox to the wrong source. First of all, I don't really see why you need to have to ObjectDataSource at all. You can just bind the ItemsSource of the ListBox to your collection, like you did.
But also (as a commenter pointed out), keep in mind that you are accessing the UI on a different thread, so you should use calls to Dispatcher to fill up your listbox. Maybe something like this.
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.
