How to P/Invoke VarArgs (variable arguments) in C#? ... or hidden junk in CLR
Recently I wrote a cheat sheet for pinvoking in .NET. Shortly after I got a question in comments about how to deal with variable arguments, when it's more, then one parameter.

Consultants for charity

Auto scroll ListBox in WPF
In WinForms era it was very simple to autoscroll listbox content in order to select last or newly added item. It become a bit complicated in WPF. However, complicated does not mean impossible.
