Refresh UI with a Timer in WPF (with BackgroundWorker?)

Question

We have an application in WPF that shows data via ObservableCollection. After 5 minutes, I want to refresh the data.

I thought I could use the System.Timers.Ti

Answer 1

Why not use a DispatcherTimer? That will "tick" in the dispatcher thread already.

Beyond that, it's hard to say what's wrong just from your description of "there's a problem with the threads".
