How to make a form always top of taskbar

Question

I want create a form in C# that always be on top of taskbar and other programs. I try with Topmost but when I click on Alt+Tab or start button on keyboard, taskbar is top of my form.

Preventing the user from using his taskbar and the windows of other apps is excessively hostile. Windows will not put up with that. The only way to do it is go whole-hog, you must create a borderless window that's maximized. — Hans Passant, Sep 17 '15 at 11:48

Ugly approach: use Timer.

private void timer1_Tick(object sender, EventArgs e)
{
    this.TopMost = true;
}

Better not to do so.

@neli - The taskbar is usually located below the desktop. What appears when you press Alt + Tab is not the taskbar. – Alexander Petrov Sep 18 '15 at 15:56
