Wpf Full Screen View using C#

in my wpf application, i want the feature like : If i click on Maximize window it should display Maximize window with windows Task bar in bottom side and when i double click anywhere on window, it should display full screen view without task bar at bottom side that is Full screen mode should be displayed.

I tried with WindowStyle to "None"

WindowState to "Maximized" and ResizeMode to "NoResize"

but in that once it should hide bottom taskbar then it wont display task bar and if once taskbar is displayed then it wont hide task bar.

Any kind of help would be appreciated.

Thank You in advance.
