WPF Databinding CheckBox.IsChecked

Question

How would I bind the IsChecked member of a CheckBox to a member variable in my form?

(I realize I can access it directly, but I am trying to learn about databinding

Addendum to @Will's answer: this is what your DependencyProperty might look like (created using Dr. WPF's snippets):

#region ShowPending

/// 

/// ShowPending Dependency Property
/// 
public static readonly DependencyProperty ShowPendingProperty =
    DependencyProperty.Register("ShowPending", typeof(bool), typeof(MainViewModel),
        new FrameworkPropertyMetadata((bool)false));

/// 

/// Gets or sets the ShowPending property. This dependency property 
/// indicates ....
/// 
public bool ShowPending
{
    get { return (bool)GetValue(ShowPendingProperty); }
    set { SetValue(ShowPendingProperty, value); }
}

#endregion
