Can I put a sfDiagram into a ContentControl of a SfDockingManager?

My simple test project is at https://drive.google.com/file/d/13O6k-3atZZOTHhgyPKZqoHTCTHk7Wtkw/view?usp=sharing

I am using VS 2019 community in windows 10 1903(18362.356).

 

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:local="using:stDesigner"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    xmlns:layout="using:Syncfusion.UI.Xaml.Controls.Layout"

    xmlns:syncDiagram="using:Syncfusion.UI.Xaml.Diagram"

    x:Class="stDesigner.MainPage"

    mc:Ignorable="d">

    

       

       

           

       

       

    

                                   

The problem I got is a exception when I start the app:

> stDesigner.exe!stDesigner.App.InitializeComponent.AnonymousMethod__5_0(object sender, Windows.UI.Xaml.UnhandledExceptionEventArgs e) Line 53 C#

The exception is:

Message = "System.NullReferenceException: Object reference not set to an instance of an object.\r\n   at Syncfusion.UI.Xaml.Diagram.SfDiagram.DiagramUnloadedEvent(Object sender, RoutedEventArgs e)"

Thanks!
