Glass Mapper SitecoreService を使用してアイテムを取得する際に問題があります。アイテムは確実に存在し、タイプは正しいです。(TDS によって生成されています)。
var language = Language.Parse("en-GB");
var service = new SitecoreService("master");
var targetPath = String.Format("{0}-migrated", Constants.SourceProviderListPageItem);
var target = service.GetItem<IProvider_List_Page>(targetPath, language);
上記のコードでは、service.GetItem<T> が呼び出されたときに次の例外が発生します。
Duplicate type name within an assembly.
