Force UI update on the fly, after changing current culture in WPF

Question

I need to support UI language change through the application menu. The texts are localized using resource files (similar to approach 1 here)

if I set the Thread.Cu

Answer 1

Assuming the DataContext for the menu is an object that implements INotifyPropertyChanged, you can refresh all controls by specifying null (nothing) in the PropertyChanged event...

from msdn:

The PropertyChanged event can indicate all properties on the object have changed by using either a null reference (Nothing in Visual Basic) or String.Empty as the property name in the PropertyChangedEventArgs.
