Get current TFS connection in a Visual Studio addin

Question

I'm working on a Visual Studio 2010 add-in, and I'm trying to figure out how to determine the currently connected TFS server. I'm guessing I need to use DTE, but I'm having a brain cramp figuring out where to get the info.

Any help is, of course, appreciated.

EDIT:

Actually, I may have found the answer, which I culled from a couple places.

    var dte = Package.GetGlobalService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;

    TeamFoundationServerExt ext = dte.GetObject("Microsoft.VisualStudio.TeamFoundation.TeamFoundationServerExt") as TeamFoundationServerExt;

    TeamFoundationServer tfs = new TeamFoundationServer(ext.ActiveProjectContext.DomainUri);
    VersionControlServer vcs = tfs.GetService<VersionControlServer>();

    var changes = vcs.GetPendingChanges(null);

I still need to clean this up a little, but it seems to work ok.
