Gee, sometimes its fun to overengineer things. There is an Aggregate function which turns a list into a scalar value – lets create one that goes the other way public static class Extensions { public static IEnumerable<T> Explode<T>(this T value, Func<T,T> next, Func<T,bool> limit) { var n = value; while(!limit(n)) { yield return n; n … Read more
I am pretty sure it is a very early, very primitive, Windows Forms only form of Multitasking You are pretty close to correct on all counts except for your conjecture that it is for WinForms only. “DoEvents” precedes WinForms; it was present in Visual Basic long before WinForms was invented, and “pump the message queue” … Read more

Since you already create (and save) your tasks, the easiest fix would be to await them for each iteration of your while loop: while (run) { action2(); foreach (Task t in continutask) await t; } That way, when all pings completed (successful or not) you start the entire process again – without delay.
