C# Wait until condition is true

Question

I am trying to write a code that executes when a condition is met. Currently, I am using while...loop, which I know is not very efficient. I am also looking at AutoResetEven

At least you can change your loop from a busy-wait to a slow poll. For example:

    while (!isExcelInteractive())
    {
        Console.WriteLine("Excel is busy");
        await Task.Delay(25);
    }
