Since Unloaded event is not called reliably for the UserControl when the hosting MFC Window closes, there is a need for another solution. XAML: < UserControl  x : Class = "Views.MyUserControl"               xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"               xmlns : x = "http://schemas.microsoft.com/winfx/2006/xaml"               xmlns : mc = "http://schemas.openxmlformats.org/markup-compatibility/2006"                 xmlns : d = "http://schemas.microsoft.com/expression/blend/2008"                 mc : Ignorable = "d"                 d : DesignHeight = "300"  d : DesignWidth = "300" >      < Grid >                   </ Grid > </ UserControl > Code Behind: using  System; using  ViewModels; name
