    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.

    Hi Cameron,

    What I can suggest you would be to check how our BusyIndicator First Look example is implemented (it loads the ScheduleView appointments through a BackgroundWorker):

    As for the exception you check the answers of the following forums and see if the proposed solutions will help.



    Hope this helps.
