}

Answer 1

调用ShowDialog（）时需要指定父窗口：

var dialogStatus = dialog.ShowDialog(System.Windows.Application.Current.MainWindow);

You are using window dialog, so you might do some more works by wrapping it into a WPF view or window. Then, set owner for WPF control

 wpfDialog.Owner = System.Windows.Application.Current.MainWindow;

This is how can you wrap it:

Hope it works.
