Executing on the wrong thread in WPF

[Montago]

I used this lib to debounce inputs from the user.

the action is executed in a different thread than UI - which means that DependencyProperties are inaccessible.

I had to wrap the inner content of the Action in a different Dispatcher:

debouncer.Debounce(() => { Application.Current.Dispatcher.BeginInvoke(new Action(() => { UpdateCarModels(); })); });

I updated the package, plus yes Application.Current.Dispatcher.BeginInvoke you have to do in your case
