How do i get a Menu in the Window bar?

Question

I would like to know how to get a menu in the window bar, the same as Visual studio does.

It would be good to be able to have File, Edit, etc on the left and the standard Minimize, Maximize and Close buttons on the right. Is this at all possible?

I have tried setting Window WindowStyle="None" and adding my own icons in the bar but it doesnt seem right but is this the only way?

This is what i have at the moment.

<Window
        Title="MainWindow" 
        Height="{x:Static SystemParameters.PrimaryScreenHeight}"
        Width="{x:Static SystemParameters.PrimaryScreenWidth}"
        Closing="Window_Closing"
        WindowState="Maximized">

You must create your custom window chrome using the WindowChrome class:

The Window element in WPF is actually hosted in a non-WPF (non-client) host. This host includes the title bar (caption) and the standard buttons, an icon and the actual frame. This is known as window chrome.

Usually you can only modify the client area of a Window. But whith the help of the WindowChrome class, WPF allows the client area to extend into the non-client area.
The disadvantage is that you would have to basically replicate the original non-client area in order to preserve the original look and feel. But after all you still get some basic behavior like maximizing the window on double click ou of the box.

The following example is very basic, but should give you an idea how to achieve your task:

I highly recommend to follow the provided link to the WindowChrome class and read the remarks section, which contains very valuable information.
You can use the actual system values provided by the static SystemParameters class to get the current dimension values e.g. SystemParameters.WindowResizeBorderThickness which you should use in your custom chrome style.

Also note that to allow WPF to capture mouse events on you custom chrome's input elements like buttons or menus you must set the attached property WindowChrome.IsHitTestVisibleInChrome on each relevant element to true:

WindowChrome.IsHitTestVisibleInChrome="True"

The very basic style that creates the above visual is as followed:
