Hey,
I am trying to get my appointments to update in a backgroundworker. I have the backgroundworker up and running but when I assign my appointments to the ObservableCollection on the viewmodel in the RunWorkerCompleted and fire the NofityPropertyChanged I get an error "Must create DependencySource on same Thread as the DependencyObject." I do not get this error when notifying of changes to strings and ints. Do you know of any reasons why the NotifyPropertyChanged would not work.
Thanks
