How do I update a Label from within a BackgroundWorker thread?

Question

When I used WinForms, I would have done this in my bg_DoWork method:

status.Invoke(new Action(() => { status.Content = e.ToString(); }));
status.Invoke(new Action(() => { status.Refresh(); }));

However in my WPF application I get an error saying that Invoke does not exist for Label.

Any help would be appreciated.

This will help you.

To Execute synchronously:

Application.Current.Dispatcher.Invoke(new Action(() => { status.Content = e.ToString(); }))

To Execute Asynchronously:

Application.Current.Dispatcher.BeginInvoke(new Action(() => { status.Content = e.ToString(); }))
