I’ve tried this code and from what I can see there’s nothing wrong with it. It may be that some library-references are out of sync (QuickGraph-GraphSharp). I recompiled the Graph#-Controls and fit it all together in the one solution. I removed the Binding in XAML and loaded the graph in the constructor of MainWindow.
The resulting graph that I get from the code is: 0 -> 1 -> 2 -> 3-> 4 and not: 1 -> 2 -> 3 -> 1-> 4. You can download the full source-code here to see for yourself.
