choosing a diagramming library for .Net [closed]

Question

I have a customer who needs to convert a diagramming application (which was developed in MFC a long time ago) to C#. The application displays large networks (lots of graphical elements), and lets the user edit/manipulate the data through a graphical ui.

I decided that it would be best to use a library rather than to develop all from scracth (all graphic objects/selection/tools/events/etc)

I am looking for a commercial solution.

I found three that seem to be very mature, and I wonder if anyone had used them and can write his/her opinon:

1. Tom Sawyer Visualization
2. IBM ILog Diagrammer for .Net
3. yWorks - yFiles for .Net

thanks Yaron
