I am following this tutorial on how to create a custom section, and have got to the implementation of GetMenuForNode().

The author demonstrates implementing the menu using an IAction implementation.

However, MenuItem has several different constructors. The one that accepts an IAction names that parameter "legacyMenu":

public MenuItem(IAction legacyMenu, string name = "")
  : this()
{
  this.Name = StringExtensions.IsNullOrWhiteSpace(name) ? legacyMenu.Alias : name;
  this.Alias = legacyMenu.Alias;
  this.SeperatorBefore = false;
  this.Icon = legacyMenu.Icon;
  this.Action = legacyMenu;
}

The word "legacy" set alarm bells off in my head - is this approach to constructing a MenuItem now obsolete? What is the alternative?
