我试图安装产品模块。我已经根据教程完成了（添加到示例几个字段）但是在重新启动应用程序后我收到了这个错误：

尚未为 ProductCatalog.Model.ProductItem 类注册元数据。（这通常表明，该类未声明为持久性，或者已声明为持久性但未增强。该类是从 file:///C:/Program Files/Telerik/Sitefinity 4.1/Projects/pssite/bin/ProductCatalog 加载的.DLL。）

堆栈跟踪：

我正在使用 SF4.1 还有其他人收到此错误吗？

在将流利的映射器用于数据模型时，这个问题几乎总是项目开放访问的错误配置。

您需要卸载项目并编辑 .csproj 文件以增强它的 openaccess。有关具体说明，请查看“与 OpenAccess Enhancer 集成”部分下的此链接：http ://www.telerik.com/help/openaccess-orm/fluent-mapping-getting-started-fluent-mapping-api.html#Integration_with_OpenAccess_Enhancer

如果这不能解决问题，请告诉我

希望这有帮助！
