Hi this is my first project I do with .NET 6 framework.

I've added the nuget package for the UltraToolbarManager, when adding the manager to a blanc form I don't see anything on the form, except a fill panel that is added

When adding the same control to .NET Framework project I can see some kind of layout manager to add buttons, change style of the menu?

After adding I've also got the following message in my outbox

[12:11:35.101424] fail: Exception occurred while disposing VSDesignSurface
System.NullReferenceException: Object reference not set to an instance of an object.

For information on how to troubleshoot the designer refer to the guide at https://aka.ms/winforms/designer/troubleshooting.

What is the now proper way to create a ribbon style menu ? Because I don't have the layout
