Thanks for your comments. I found a solution. After Nick Baker’s comment I googled Dispatcher.Invoke. After reading and testing I found this page

WPF: Running code when Window rendering is completed http://geekswithblogs.net/ilich/archive/2012/10/16/running-code-when-windows-rendering-is-completed.aspx

Then I changed my code to the following (not the complete code, just the relevant parts):

private void Work(){
    List<Artist> selectedArtistsList;
    //Code to fill selectedArtistsList with about 6,000 items not shown here
    CollectionViewSource selection1ViewSource = ((CollectionViewSource)(this.FindResource("selection1Source")));
    stopWatch1.Reset();
    stopWatch1.Start();
    selection1ViewSource.Source = selectedArtistsList;
    Debug.Print("After setting Source: {0}ms", stopWatch1.ElapsedMilliseconds.ToString());

    //New:
    Dispatcher.BeginInvoke(new Action(RenderingDone), System.Windows.Threading.DispatcherPriority.ContextIdle, null);
}

//New
Stopwatch stopWatch1 = new Stopwatch();
private void RenderingDone() {
    Debug.Print("After rendering is done: {0}ms", stopWatch1.ElapsedMilliseconds.ToString());
}

After running this I see: After setting Source: 124ms After rendering is done: 2273ms

The last line appear after the rendering is done and it shows the correct time. This is exactly what I wanted.
