Getting error XDG0008 when trying System.Windows.Controls.Ribbon example

Question

Coded the example shown in Microsoft documentation for System.Windows.Controls.Ribbon with URL: https://learn.microsoft.com/en-us/dotnet/api/system.windows.controls.ribbon.ribbon?view=windowsdesktop-6.0. I had to modify MainWindow.xaml.cs to avoid an error using the code
`using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls.Ribbon;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace CtrlRibbonRibbon;

/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : RibbonWindow
{
public MainWindow ()
{
InitializeComponent ();
}
}
`
However, the MainWindow.xaml reports the error: The name "RibbonWindow" does not exist in the namespace "clr-namespace:System.Windows.Controls.Ribbon". at line 4 of the following XAML
<ribbon:RibbonWindow x:Class="CtrlRibbonRibbon.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:ribbon="clr-namespace:System.Windows.Controls.Ribbon"
Title="MainWindow"
x:Name="RibbonWindow"
Width="640" Height="480">

The documentation shows that RibbonWindow is a class in System.Windows.Controls.Ribbon and the dependencies show that namespace has been loaded. So why am I getting that error?

You could replace the code xmlns:ribbon="clr-namespace:System.Windows.Controls.Ribbon" with the following code

xmlns:ribbon="clr-namespace:System.Windows.Controls.Ribbon;assembly=System.Windows.Controls.Ribbon"  

complete code:

xaml:

<ribbon:RibbonWindow x:Class="CtrlRibbonRibbon.MainWindow"  
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"  
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"  
        xmlns:local="clr-namespace:CtrlRibbonRibbon"  
        xmlns:ribbon="clr-namespace:System.Windows.Controls.Ribbon;assembly=System.Windows.Controls.Ribbon"  
        mc:Ignorable="d"  
        Title="MainWindow" Height="450" Width="800">  
    <Grid>  
          
    </Grid>  
</ribbon:RibbonWindow>  

Codebedhind:

using System.Windows.Controls.Ribbon;

public partial class MainWindow : RibbonWindow  
    {  
        public MainWindow()  
        {  
            InitializeComponent();  
        }  
    }
