As you can see here, the corner is white, I want it to be transparent, and I know things can go wrong with WPF where transparent becomes white but then I could just change the color to the background color.
So my question is, which property is it that I need to change to make sure that the corner right there isn't white?

You should set the Background property of the parent Menu element:
<Menu Background="Transparent" ...>
We have been tasked with designing an enterprise application in WPF that will replace a battleship grey Winforms application with a modern look and feel.
We like the look and feel that Microsoft web applications currently possess:
We could create these menus in WPF in the usual way:
<DockPanel>
<Menu DockPanel.Dock="Top">
<MenuItem Header="_File">
<MenuItem Header="_New" />
<MenuItem Header="_Open" />
<MenuItem Header="_Save" />
<Separator />
<MenuItem Header="_Exit" />
</MenuItem>
</Menu>
<TextBox AcceptsReturn="True" />
</DockPanel>
But we'd get something that looks like a Winforms menu.
I've seen some rather impressive styling efforts like this one, but they all seem to have the same familiar Winforms shape. I've also seen menus in libraries like MahApps Metro, but these strike us as too spartan.
Is the WPF Menu control flexible enough to be styled as shown in the picture above, or should we go another route like building a custom menu control from Stack Panels and Lists? What are the tradeoffs?
Bonus points (i.e. a bounty) will be awarded for xaml/code that does exactly this.
An example of this menu style in action:
https://www.visualstudio.com/
WPF was really designed with the possibility to change the look and behavior of every out-of-the-box mechanisms / controls (buttons, menus, treeview, etc.).
So, in general, it's better to do this rather than to rewrite everything. For example, if you redesign your custom menu, you'll have to think about keyboard, UI automation, etc...
So, I gave a shot at your example and tried to build a minimum working sample - pure XAML - that mimics VS online menu (I've also added the hover background color change that's not by default in WPF's menu).
Here is the result and, as you see, it looks very similar:
Here is the XAML. I've chosen to use a custom control template per each MenuItem. I think it's quite practical when you need to really customize every item.

You are probably looking for some Wpf Theme to start with.
Such as
http://brianlagunas.com/free-metro-light-and-dark-themes-for-wpf-and-silverlight-microsoft-controls/
or have a look at that SO answer:
Any free WPF themes?
Then you probably would want to customize it even more with look and feel you are looking for.
You could use something like: http://materialdesigninxaml.net
This is the default menu, but white, you can change the background color, text font, height, and everything else you want just by editing this style.
Here your MainWindow.xaml

<!-- Menu End -->
I would create the menu with XAML
XAML of Page something like this:
<Window.Resources>
<Style TargetType="TextBlock">
<Setter Property="Margin" Value="10" />
<Setter Property="FontSize" Value="15" />
<Setter Property="Foreground" Value="White" />
</Style>
</Window.Resources>
<Grid x:Name="Content">
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<StackPanel Orientation="Horizontal" Background="CornflowerBlue">
<TextBlock Text="Menu1" MouseLeftButtonDown="OnMouseLeftButtonDown" />
<TextBlock Text="Menu2" MouseLeftButtonDown="OnMouseLeftButtonDown" />
<TextBlock Text="Menu3" MouseLeftButtonDown="OnMouseLeftButtonDown" />
</StackPanel>
<Border Grid.Row="1" Background="Bisque"></Border>
</Grid>
</Grid>
And in Code:
private void OnMouseLeftButtonDown(object sender, MouseEventArgs e) {
var textBlock = sender as TextBlock;
if (textBlock == null) return;
var relativePoint = VisualTreeHelper.GetOffset(textBlock);//textBlock.TransformToAncestor(Content).Transform(new Point(0, 0));
//Almost invisible Background - If the user clicks it the menu is hidden
var back = new Border{Background = new SolidColorBrush(Color.FromArgb(1,255,255,255))};
back.MouseLeftButtonDown += (o, args) => {
Content.Children.Remove(back.Tag as UIElement);
Content.Children.Remove(back);
};
Content.Children.Add(back);
//Build menu
var menu = new Border{Background = new SolidColorBrush(Colors.White), Width = 200, Height = 500, BorderBrush = new SolidColorBrush(Colors.Gray), BorderThickness = new Thickness(1), HorizontalAlignment = HorizontalAlignment.Left, VerticalAlignment = VerticalAlignment.Top};
back.Tag = menu;
menu.RenderTransform = new TranslateTransform(relativePoint.X, relativePoint.Y + textBlock.ActualHeight + 5);
//Do some more styling
//Fill Menu here according to the tag of the TextBlock (switch(textBlock.Tag){...} or use a predefined view
Content.Children.Add(menu);
//Hide the Menu on click - TODO Implement logic to hide menu if a MenuItem was clicked...
menu.MouseLeftButtonDown += (o, args) => {
Content.Children.Remove(back.Tag as UIElement);
Content.Children.Remove(back);
};
}
OK, this is a very basic example and needs a lot of improvement but I think you can work on it...
Reading lots of stuff and asking a bunch of questions I have finally put together a new style for my Menu/MenuItem in WPF.
But I'm stuck where I want to change the background and border of a single submenu when it is highlighted.
In the image below, I want the blue background to be changed to say yellow!
Here is the complete working code so far:

Just make another template. Here is one with the background yellow, border orange and text black.
Look at MenuItemControlTemplate2, the IsHighlighted trigger.

I am creating Custom ComboBox. Here I am trying to get BorderBrush value from ComboBox's TemplateBinding. But I am not getting it. It is always white. I dont know why it is happening, may be my way of getting the Brush is wrong.
Please suggest.
