You can use the Menu and the MenuItem classes in WPF. Here is the code that creates a menu bar in WPF.
<Grid x:Name="LayoutRoot">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Menu Height="38" Name="menu1" Margin="10,10,344,0" VerticalAlignment="Top" BorderThickness="2" Foreground="White" FontSize="16" FontWeight="Bold">
<Menu.Background>
<LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#FF3A60AD" Offset="0.528" />
<GradientStop Color="#FF6A85D8" Offset="0.01" />
<GradientStop Color="#FF3464C4" Offset="1" />
<GradientStop Color="#FF202E7E" Offset="1" />
</LinearGradientBrush>
</Menu.Background>
<Menu.BitmapEffect>
<DropShadowBitmapEffect />
</Menu.BitmapEffect>
<MenuItem Header="Tools" IsCheckable="true">
<MenuItem.Icon>
<Image Source="Tools.png" Width="20" Height="20" />
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="Settings" IsCheckable="true" Foreground="Orange" FontSize="16">
<MenuItem.Icon>
<Image Source="Settings.png" Width="20" Height="20" />
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="Security" IsCheckable="true" Foreground="White" FontSize="16">
<MenuItem.Icon>
<Image Source="Security.png" Width="20" Height="20" />
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="Database" IsCheckable="true" Foreground="LightGreen" FontSize="16">
<MenuItem.Icon>
<Image Source="Database.png" Width="20" Height="20" />
</MenuItem.Icon>
<MenuItem.Background>
<ImageBrush ImageSource="Database.png" Stretch="Fill" />
</MenuItem.Background>
</MenuItem>
</Menu>
</Grid>

`Menu mainMenu = newMenu();
mainMenu.Background = Brushes.LightGreen;
mainMenu.Height = 300;
mainMenu.Width = 200;
MenuItem item1 = newMenuItem();
item1.Width = 50;
item1.Header = “First”;
mainMenu.Items.Add(item1);
MenuItem item2 = newMenuItem();
item2.Width = 50;
item2.Header = “Two”;
item1.Items.Add(item2);
MenuItem item3 = newMenuItem();
