How can I bind an ItemsControl.ItemsSource with a property in XAML?

Question

I have a simple window :

<Window x:Class="WinActivityManager"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Grid>
        <ListView x:Name="lvItems" />
    </Grid>
</Window>

And the associated code behind :

public partial class WinActivityManager : Window
{
    private ObservableCollection<Activity> Activities { get; set; }

    public WinActivityManager()
    {
        Activities = new ObservableCollection<Activity>();
        InitializeComponent();
    }

    // Other code ...
}

If I write the following binding in the window constructor :

lvItems.ItemsSource = Activities;

then my ListView is automatically updated when I add or remove elements from Activities.

How should I write the binding in XAML?
I tried this but it doesn't work:

<ListView x:Name="lvItems" ItemsSource="{Binding=Activities}" />

How do I make this work in XAML?

What @JesseJames says is true but not enough.

You have to put

private ObservableCollection<Activity> Activities { get; set; } 

as

public ObservableCollection<Activity> Activities { get; set; }

And the binding should be:

<ListView x:Name="lvItems" ItemsSource="{Binding Path=Activities}" />
