c# - Show a winform over the notification area

Question

I want to show a winform in the very right down corner just above the system tray,

How do I do that? Here is my code:

public static void Notify()
{        
    Rectangle workingArea = Screen.PrimaryScreen.WorkingArea;
    Form fm = new Form();
    fm.ClientSize = new Size(200, 200);
    int left = workingArea.Width - fm.Width;
    int top = workingArea.Height - fm.Height;
    fm.Location = new Point(left, top);
    fm.ShowInTaskbar = false;
    fm.ShowIcon = false;
    fm.MinimizeBox = false;
    fm.MaximizeBox = false;
    fm.FormBorderStyle = FormBorderStyle.FixedToolWindow;
    fm.Text = "Test";
    fm.TopMost = true;
    fm.Show();
}

I just tried this and it worked for me (note: this code must appear after the form has been displayed for the first time -- for example, you can put it in the form's Load event handler, or simply include it after any call to Show):

Rectangle workingArea = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea;
int left = workingArea.Width - this.Width;
int top = workingArea.Height - this.Height;

this.Location = new Point(left, top);

Whether to use WorkingArea or Bounds depends on what you mean by "over": if you mean "in front of," then use Bounds, as it includes the area covering the entire screen (including that space occupied by the system tray); if you mean "above," then use WorkingArea, which just includes the user's desktop.

Also let me just clarify that you want your actual form displayed down there, right? If you wanted an icon in the notification area, that's what the NotifyIcon component is for.
