manages the global navigation and the current navigation (the standard navigation schemes).
Assembly: Microsoft.SharePoint.Publishing (in Microsoft.SharePoint.Publishing.dll)
The GlobalNavigation scheme typically includes a navigation menu that appears at the top of the master page, while the CurrentNavigation typically includes a navigation menu that appears on the left side of the master page.
Behind the scenes, the high-level global and current navigation providers correspond to a number of low-level configurations that need to be specified in a WebNavigationSettings object. As an API, StandardNavigationSettings is the easiest one to use but it has limited functionality. For example, configuring an auxiliary TaxonomySiteMapProvider object can be done only by using a SiteMapProviderSettingsList collection.
