OK, so I'm close to done with this, but there's still a related problem.

In the MainWindow's code behind I have
NavigationPaneInfos = new List<NavigationPaneModel>
{
    new NavigationPaneModel
    {
        Header = "Projects", 
        NavigationItemType = NavigationItemType.Project, 
        DataSource = Repository.GetNavigationItems,
        IsExpanded = true                        //<=== THIS TRIGGERS LOAD
    },

    new NavigationPaneModel
    {
        Header = "Inventory", 
        NavigationItemType = NavigationItemType.Inventory,
        DataSource = Repository.GetNavigationItems
    },

    new NavigationPaneModel
    {
        Header = "Companies" , 
        NavigationItemType = NavigationItemType.Company,
        DataSource = Repository.GetNavigationItems,
        IsExpanded = true                        //<=== THIS TRIGGERS LOAD
    },

    new NavigationPaneModel
    {
        Header = "Employees", 
        NavigationItemType = NavigationItemType.Employee,
        DataSource = Repository.GetNavigationItems
    }
};
Here's the Pane's NavigationModel DP
public static readonly DependencyProperty NavigationPaneModelProperty =
            DependencyProperty.Register("NavigationPaneModel",
            typeof(NavigationPaneModel),
            typeof(NavigationPane),
            new PropertyMetadata(null, new PropertyChangedCallback(OnNavigationPaneModelChanged)));

public NavigationPaneModel NavigationPaneModel
{
    get { return (NavigationPaneModel)GetValue(NavigationPaneModelProperty); }
    set { SetValue(NavigationPaneModelProperty, value); }
}
private static async void OnNavigationPaneModelChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
    var control = (NavigationPane)d;

    /***********************************************************
        * This code checks to see if the Model's IsExpanded is set to True, 
        * and if it is, sets the IsPaneExpanded DP accordingly, which triggers 
        * load. below
        * 
        * See the IsPaneExpanded DP below
        * 
        **********************************************************/
    if (control.NavigationPaneModel.IsExpanded)
    {
        control.IsPaneExpanded = true;
    }
}
The IsPaneExpanded DP
public static readonly DependencyProperty IsPaneExpandedProperty =
            DependencyProperty.Register("IsPaneExpanded",
            typeof(bool),
            typeof(NavigationPane),
            new PropertyMetadata(false, new PropertyChangedCallback(OnIsPaneExpandedChanged)));

public bool IsPaneExpanded
{
    get { return (bool)GetValue(IsPaneExpandedProperty); }
    set { SetValue(IsPaneExpandedProperty, value); }
}

private static async void OnIsPaneExpandedChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
    var control = (NavigationPane)d;

    // This is getting called, but...
    if (control.IsPaneExpanded)
    {

        /********************************************************
        * Put a breakpoint here and expanded the pane manually.  
        * NavigationPaneModel will be NULL 
        * 
        * When the it's expanded from OnNavigationPaneModelChanged the 
        * the NavigationPaneModel is NOT NULL.
        *
        * It seems to go null AFTER the control is up & running
        ********************************************************/
        if (control.NavigationPaneModel != null)
        {
            await control.Load();
        }
    }
}

In addition, even though IsPaneExpanded is getting set to True, the pane never expands. I'm not getting any binding errors, and you can see the code behind is getting called.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
