I agree with many here, but I also think it depends.

Recently I did this code:

private void animate(FlowLayoutPanel element, int start, int end)
{
    bool asc = end > start;
    element.Show();
    while (start != end) {
        start += asc ? 1 : -1;
        element.Height = start;
        Thread.Sleep(1);
    }
    if (!asc)
    {
        element.Hide();
    }
    element.Focus();
}

It was a simple animate-function, and I used Thread.Sleep on it.

My conclusion, if it does the job, use it.
