Refer to active Window in WPF?

Question

How can I refer to active Window of WPF application in C#, using something like ActiveForm property in WinForms?

Accepted Answer

One possible way would be to scan the list of open windows in the application and check which one of them has `IsActive = true`:

```
Application.Current.Windows.OfType<Window>().SingleOrDefault(x => x.IsActive);
```

Not sure if there may be more than one active window if, for example, there's a modal dialog showing, in which case, the owner of the dialog and the dialog itself might be active.
