Every time I update the version number, the users first have to uninstall the previous version before they can install the new one.

I've got a large WinForms form with tab control, many many control...
Does anyone have any success with WinForms ChartFX 6.2 on Vista or Windows? I'm after a sanity check that it's not just our code. If it's a known issue I can say that upgrading is the only solution.

I'd like to display a string that containts html code (mainly for formating purposes like italic, bold, indentation, colors etc.) from a C# console application.

Hi All I'd like my app to be able to communicate with itself via the internet but this is proving to be impossible for me. One thing I've never been able to work out is Tcp or the whole networking thing in general. I have read the docs and seen literally over 30 samples, none of which have ever worked. All I'm trying to do is send a m...
