VB.net Borderless Form Maximize over Taskbar

When I maximize my borderless form, the form covers the entire screen including the taskbar, which I don't want it to do. I'm finding it very difficult to find a solution to my problem on the net, all I've come up with is the below code, which displays the taskbar for a short time, but then disappears and the form still takes up the entire screen.

Private Sub TableLayoutPanel1_DoubleClick(sender As Object, e As MouseEventArgs) Handles TableLayoutPanel1.DoubleClick
If e.Location.Y < 30 Then
Me.WindowState = FormWindowState.Maximized
Me.ControlBox = True
End If
End Sub

I'm starting to think the only way to solve my problem is to find the screen size height minus the taskbar height to get the form height, but I'm hoping there might be a simpler answer.

Use the form's Load event to set its maximum size, like this:

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Me.MaximumSize = Screen.FromRectangle(Me.Bounds).WorkingArea.Size
End Sub

Maximizing it now restricts the size to the monitor's working area, which is the monitor size minus the taskbars.
