Win10 UAP: swapchain panel doesn't exist?

I created a brand new UAP project using a dev build of MonoGame from last week. The GamePage.xaml.cs file created for me doesn’t compile, as it seems to be referencing a non-existant SwapChainPanel component - which I assume is deprecated as it’s not available in the VS2015 XAML tools picker

Also, this.initialiseComponent() doesn’t exist

    public sealed partial class GamePage : Page
	readonly Game1 _game;

	public GamePage()

		// Create the game.
		var launchArguments = string.Empty;
        _game = MonoGame.Framework.XamlGame<Game1>.Create(launchArguments, Window.Current.CoreWindow, swapChainPanel);

What do I need to do to fix this? Looks like MonoGame.Framework.XamlGame.Create requires a non-existant SwapChainPanel!

Turned out to be mangled namespaces in the XAML. When I imported the existing code into the new Universal Windows project, I changed the namespaces in code but not in the XAML files.
