Invoking a WPF view (UserControl) method from the main window (Window) - wpf

Question

I have a button on a view (UserControl) that invokes a method in the code-behind file. I would like to get rid of the button and instead, invoke the method from a menu item. Not sure how to do this. Here is some simple code illustrating this situation:
MainWindow.xaml (MainView is embedded):
<Window x:Class="Example.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:View="clr-namespace:Example.View"
Title="MainWindow" Height="600" Width="800" Background="Green">
<Grid>
<StackPanel>
<Menu>
<MenuItem Header="File" Click="MenuItem_Click">
</MenuItem>
</Menu>
<View:MainView/>
</StackPanel>
</Grid>
MainWindow.xaml.cs
using System.Windows;
namespace Example
{
public partial class MainWindow : Window
{
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("MainWindow");
// how can I invoke MainView methods like DoWork from here?
}
}
}
MainView.xaml
<UserControl x:Class="Example.View.MainView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" d:DesignHeight="500" d:DesignWidth="600">
<Grid Background="Yellow">
<Button HorizontalAlignment="Left" VerticalAlignment="Top" Margin="10" Content="Show" Click="Button_Click"/>
</Grid>
</UserControl>
MainView.xaml.cs
using System.Windows.Controls;
namespace Example.View
{
public partial class MainView : UserControl
{
public MainView()
{
InitializeComponent();
}
private void Button_Click(object sender, System.Windows.RoutedEventArgs e)
{
DoWork();
}
public void DoWork()
{
MessageBox.Show("MainView");
}
}
}

You could just give a name to the MainView,
<Window x:Class="Example.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:View="clr-namespace:Example.View"
Title="MainWindow" Height="600" Width="800" Background="Green">
<Grid>
<StackPanel>
<Menu>
<MenuItem Header="File" Click="MenuItem_Click"/>
</Menu>
<View:MainView x:Name="mainView"/>
</StackPanel>
</Grid>
</Window>
and call the Method like this:
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
mainView.DoWork();
}
