.net RouteUrl和RouteLink不工作

我刚刚升级到MVC3 final，我的一部分网站已经完全停止工作。你知道我的网址到哪里去了，或者怎么把它们找回来吗

最终证明是路由和不正确正则表达式需要默认值的变化

routes.MapRoute(
            "SingleArticle",
            "Articles/{action}/{year}/{month}/{day}/{key}", 
            new { controller = "Articles", action = "Archive", year = 0, month = 0, day = 0, key = "" },
            new { year = @"\d{4}", month = @"\d{2}", day = @"\d{2}" }
        );

        var routeLinkData = new { 
        action = "Archive", 
        year = item.PublishDate.Value.Year, 
        month = item.PublishDate.Value.Month, 
        day = item.PublishDate.Value.Day, 
        key = item.NameKey };

        URL="@Url.RouteUrl("SingleArticle", routeLinkData)"
        Link="<a href="@Url.RouteUrl("SingleArticle", routeLinkData)">Link</a>"

       URL=""
       Link="<a href="">Link</a>"
