C# 用户代码未处理Telerik.OpenAccess.OpenAccessException

下面是我得到的错误。请帮忙

Telerik.OpenAccess.OpenAccessException was unhandled by user code
  Message=No metadata has been registered for class Ind.Data.IndiStage.Academy. (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:/Users/suresh/Documents/WorkSpace/Ind_folder/Ind.ETLService/bin/Release/Ind.Data.IndiStage.DLL.)

哇。 我很难摆脱这个例外。Telerik OpenAccess“尚未为类注册元数据”

阅读这篇文章，特别是你使用像TeamCity这样的CI构建系统：

需要更多信息。你试过在学院课堂上添加“元数据”吗？它不是声明为持久的还是持久的但没有增强的？从探索错误消息开始，寻找合理的解决方案。
