Apart from getting selecting nodes in the Solution Explorer and selecting them, some people want to do the same with the Server Explorer. There is mixed news here: while you can navigate the Server Explorer like you do with the Solution Explorer (its inner object is an EnvDTE.UIHierarchy), the UIHierarchyItem.Object property of each node is useless, since it returns the UIHierarchyItem type (on the contrary, nodes of the Solution Explorer return EnvDTE.Solution, EnvDTE.Project, EnvDTE.ProjectItem, etc.).

So, this new article only shows how to get the names of the nodes. Also, notice that the Server Explorer inner object can not be retrieved directly using EnvDTE80.DTE2.ToolWindows (as you do with the Solution Explorer using EnvDTE80.DTE2.ToolWindows.SolutionExplorer), and while you could use EnvDTE80.DTE2.ToolWindows.GetToolWindow(“Server Explorer”), that would work only on the English version of Visual Studio. The article shows an international solution:
