Loaded does not exist on inherited BaseDiagramPage

I have a BaseDiagramPage class which inherits directly from Page. The idea is that it will hold common functionality across multiple pages (let me know if this is a bad way to do it). But my XAML classes implementing BaseDiagramPage are complaining that this.Loaded does not exist. It works fine if I inherit from Page directly in the XAML class.

The BaseDiagramPage class can literally have nothing in it.

Any insights would be appreciated.

public sealed partial class EmptyPage : BaseDiagramPage
{
    public EmptyPage()
    {
        this.InitializeComponent();

        // this property does not exist, BaseDiagramPage is public
        this.Loaded += (sender, e) =>
        {
            // load something
        };
    }
}

EDIT:

BaseDiagramPage source

namespace CoreProject.Pages
{
    public class BaseDiagramPage : Page
    {

    }
}

EDIT EDIT:

Using base.Loaded works, but is that right? I want to call my classes Loaded

base.Loaded += (sender, e) =>
{
};

I think you forgot to change the XAML part of your EmptyPage, so just change

<Page x:Class="xxx.EmptyPage" ...>
    ...
</Page>

to

<local:BaseDiagramPage x:Class="xxx.EmptyPage" ...>
    ...
</local:BaseDiagramPage>

After doing this, you can even remove the inheritance from your C# code as it's now redundant. So the following would just work.

public sealed partial class EmptyPage
