ASP.NET MVC SiteMap provider -- How to 'hide' single items in the actual menu

Question

I am using the ASP.NET MVC SiteMap provider in a project, and it is working great. I am having a tough time trying to figure out how to hide a menu item however. The menu item I want to hide from displaying in the global navigation is my "Site Map" page. Now I know that there is something called a VisibilityProvider available to me on the mvcSiteMapNode - but I can't seem to figure out how to make it work.

First, I suggest you read this wiki page: Creating a Custom SiteMapNodeVisibilityProvider. Then for the specific node that points to your Site Map page, declare it this way:

<mvcSiteMapNode title="Site Map" controller="Home" action="Map" visibility="false" />

Now, when implementing the IsVisible method (shown in the wiki page linked above), you can do this:

string visibility = mvcNode["visibility"];

// Is a visibility attribute specified?
if (!string.IsNullOrEmpty(visibility))
{
     isVisible = Convert.ToBoolean(mvcNode["visibility"]);

     if (!isVisible)
     {
          return false;
     }
}

return true;
