There is known "airspace "issue related to WindowsFormsHost used in WPF.
I use AvalonDock with some panes, one of them hosts a WindowsForms control.
I also use MetroWindow as a popup for showing informations.
Unfortunately when popup is being shown and under it is AvalonDock.Pane with hosted window visible then it is always on most top.
Do you have any suggestions how to solve this issue?
MetroWindow has some properties as MetroWindow.Topmost but it does not work as I expected.
