Cleaning up after calls to SMO Server and Database

How do you make SMO release it's connections?

I have this code:

public static class SqlServerConnectionFactory
{
    public static Server GetSmoServer()
    {
        using (var c = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString))
        {
            var s = new ServerConnection(c);
            c.Close();
            return new Server(s);
        }
    }

    public static Database GetSmoDatabase(Server server)
    {
        var db = server.Databases[ConfigurationManager.AppSettings["Database"]];
        db.AutoClose = true;
        return db;
    }
}

Called like this from an ASP.Net MVC app run in IIS...:

public ActionResult Index()
    {
        server = SqlServerConnectionFactory.GetSmoServer();
        database = SqlServerConnectionFactory.GetSmoDatabase(server);
        var vm = new SettingsIndexViewmodel(database);
        return View(vm);
    }

For every call I make to this index method a connection is spun up - and is not released again.

So after 20 calls to the page, I have 20 of the connections awaiting command. This eventually ends up with an exception, when I cannot make new connections, because the connection pool is full.

What do I need to avoid this happening? I cannot seem to find a method on the SMO Server object like Dispose, close or similar.
