It is because some information is saved in the memory. So if you want to call it everytime you login subscribe to the loaded event.
So in your construvtor write this.loaded += and what you want this will allways be called.
Frage
I have a constructor with data to be loaded when the Application run for the first time. However when I press back to exit my application, I can no longer load the constructor once I launch the application again. However this problem will not exist when I press the window button and proceed to select my application. The constructor data will still be loaded for this scenario:
public MainPage()
{
InitializeComponent();
loadData();
}
