Sitefinity 4.1自定义模块

Question

我试着安装产品模块。我是在教程的基础上完成的(添加了一些示例字段)，但是在重新声明应用程序之后，我得到了以下错误：

没有为类ProductCatalog.Model.ProductItem注册元数据。(这通常表示该类不是声明为持久的，也不是声明为持久的，而是未增强的。该类是从file:///C:/Program Files/Telerik/Sitefinity4.1/Projects/pssite/bin/ProductCatalog.dll加载的。

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，还有其他人收到这个错误吗？

当您的数据模型使用fluent映射器时，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文件以增强其以进行开放访问。有关具体说明，请查看“与OpenAccess增强器集成”一节中的链接：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

希望这能帮上忙！
