wpf - How to close a window in c# -

-

i've got following code in window b started in own thread window a.

view.closing += (sender, e) => {     view.visibility = visibility.collapsed;     e.cancel = true; };

when close window window b remains in memory , application doesn't dispose. how should go forward make sure application shut down when closing window a.

edit: window b takes while load , build that's why code there.

use application.exit();

for wpf: application.current.shutdown();
