自定义属性编辑器无法在VS2022上工作

我想为我的组件的属性创建一个自定义属性编辑器。为此,我在DemoControls项目(WinForms控件库,.NET 6)中创建了一个组件和一个属性编辑器:

public partial class UserControl1 : UserControl
{
    [Editor(typeof(CustomKeyEditor), typeof(UITypeEditor))]
    public string CustomKey { get; set; }

    public UserControl1()
    {
        InitializeComponent();
    }
}

public class CustomKeyEditor : UITypeEditor
{
    public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)
    {
        return UITypeEditorEditStyle.Modal;
    }

    public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
    {
        IWindowsFormsEditorService service = (IWindowsFormsEditorService)provider.GetService(typeof(IWindowsFormsEditorService));

        //...

        return "12";
    }
}

之后,我将DemoControls项目添加到Demo项目引用中,并将UserControl1组件添加到Form1中,如图所示:

但是,CustomKeyEditor不在编辑模式下工作,而是在运行时模式下工作。

然后我找到了这个例子并构建: https://learn.microsoft.com/en-us/dotnet/api/system.drawing.design.uitypeeditor?view=windowsdesktop-6.0

但这个例子也不起作用。

对于所有的项目,我都使用了.NET6。如果我使用.NET Framework 4.8,我的所有代码都能正常工作:
