Why ChartFX.Lite use UDP connection? in Windows Forms Posted August 4, 2011 · Report reply Hello. I decided to use ChartFX.Litecontrol in my program. I install it in my computer and with Visual Studio 2010 made test exe. It works fine in my computer, but when I start it in other computer without instalation of chart I noticed that the exe opened UDP connection on port 4494. Why does it do this? I am afraid of my clients will notice this and they will think that my program spe them. Can I stop this future of chart?
