When I try to do this:
progress.Visibility = Visibility.Visible; // it just a UI element
var t = Task.Run(() => this.CompareAll()); // CompareAll() is a time consuming operation
t.ContinueWith((result)=> { progress.Visibility = Visibility.Hidden; });
I get the following error:
"The calling thread cannot access this object because a different thread owns it".
I think I have to use something related to Dispatcher but I'm not sure how. I'm using WPF. Any ideas?
