Question

我试图安装Products模块。我已经完成了基于教程（添加到几个字段的示例）但在重新设置应用程序后我得到了这个错误：

没有为ProductCatalog.Model.ProductItem类注册元数据。（这通常表示，此类未声明为持久性或者声明为持久但未增强。该类是从file：/// C：/ Program Files / Telerik / Sitefinity 4.1 / Projects / pssite / bin / ProductCatalog加载的.DLL。）

堆栈跟踪：

[OpenAccessException: No metadata has been registered for class ProductCatalog.Model.ProductItem. (This usually indicates, that either this class is not declared persistent or it is declared persistent but not enhanced. The class was loaded from file:///C:/Program Files/Telerik/Sitefinity 4.1/Projects/pssite/bin/ProductCatalog.DLL.)]

我正在使用SF4.1 有没有其他人得到这个错误？

当您为数据模型使用流畅的映射器时，此问题几乎总是对项目的开放访问配置错误。

您需要卸载项目并编辑.csproj文件以增强openaccess。有关具体说明，请查看＆＃34;与OpenAccess Enhancer集成＆＃34;：http://www.telerik.com/help/openaccess-orm/fluent-mapping-getting-started-fluent-mapping-api.html#Integration_with_OpenAccess_Enhancer
