designer - Creates an Object of the specified type at design-time and adds it to the design document (XAML) in WPF

Question

I need to write design-time part of my Control.

In the code I need to create new Object (TextColumn) and add it to the Collection (Columns). The changes must be reflected in XAML document. How can I do it?

In WinForms I used IDesignerHost.CreateComponent method.

WinForms

  IServiceProvider srvProvider;

  IDesignerHost host = (IDesignerHost)srvProvider.GetService(typeof(IDesignerHost));
  PropertyAxisBar band = (PropertyAxisBar)host.CreateComponent(itemType);

But I cant find any Documentation or Example for WPF.

I explored documentation - WPF Designer Extensibility https://docs.microsoft.com/en-us/previous-versions/bb546938(v=vs.110)?redirectedfrom=MSDN

and Demo project - XAML Designer Extensibility Documents & Samples https://github.com/microsoft/xaml-designer-extensibility

Unfortunately, these sections do not describe how to create objects that reflect changes in a XAML document.
