In ViewModelA there is Property X. ViewModelB is InterestedIn ViewModelA.
When Property X is Changed ViewModelB have to show in the method OnViewModelPropertyChanged a catel:Datawindow with uiVisualizerService.
So I get an InvalidOperationException:
Collection was modified; enumeration operation may not execute.
in the setter of the Property X.
