6.1 SDK VSShell Output Window or equivalent?

In the old SDK I did this:

            var sp = VSShell.Instance.ServiceProvider;
            win = sp.GetService<SVsOutputWindow,IVsOutputWindow>();
            rguidPane = new Guid("46620EC4-2D3E-4F19-84F9-8BE43C23B93A");
            win.CreatePane(rguidPane, "StringTemplate Plugin", 1, 1);
            win.GetPane(rguidPane, out pane);
