Make WPF Application Fullscreen (Cover startmenu)

I would like to make my WPF application fullscreen. Right now the start menu prevents it from covering everything and shifts my application up. This is what I have for my MainWindow.xaml code:

<Window x:Class="HTA.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    mc:Ignorable="d" 
    WindowStyle="None" ResizeMode="NoResize"
    WindowStartupLocation="CenterScreen" 
    Width="1024" Height="768">

When you're doing it by code the trick is to call

WindowStyle = WindowStyle.None;

first and then

WindowState = WindowState.Maximized;

to get it to display over the Taskbar.

If you want user to change between WindowStyle.SingleBorderWindow and WindowStyle.None at runtime you can bring this at code behind:

Make application fullscreen:

RootWindow.Visibility = Visibility.Collapsed;
RootWindow.WindowStyle = WindowStyle.None;
RootWindow.ResizeMode = ResizeMode.NoResize;
RootWindow.WindowState = WindowState.Maximized;
RootWindow.Topmost = true;
RootWindow.Visibility = Visibility.Visible;

Return to single border style:

RootWindow.WindowStyle = WindowStyle.SingleBorderWindow;
RootWindow.ResizeMode = ResizeMode.CanResize;
RootWindow.Topmost = false;

Note that without RootWindow.Visibility property your window will not cover start menu, however you can skip this step if you making application fullscreen once at startup.
