实际发生的问题,因为我改变项目名称StudentSys到StudentMgmSystem
变了样下面的问题解决
<EntityTypeShape EntityType="StudentMgmSystemModel.Login" Width="1.5" PointX="0.75" PointY="0.75" IsExpanded="true" />
<EntityTypeShape EntityType="StudentMgmSystemModel.HostelDetail" Width="1.5" PointX="5.375" PointY="0.75" />
<EntityTypeShape EntityType="StudentMgmSystemModel.PersonalInfo" Width="1.5" PointX="2.75" PointY="0.875" />
<EntityTypeShape EntityType="StudentSysModel.Login" Width="1.5" PointX="0.75" PointY="0.75" IsExpanded="true" />
<EntityTypeShape EntityType="StudentSysModel.HostelDetail" Width="1.5" PointX="5.375" PointY="0.75" />
<EntityTypeShape EntityType="StudentSysModel.PersonalInfo" Width="1.5" PointX="2.75" PointY="0.875" />
好像您将两个前级后名称为'PersonalInfo' – CodeNotFound
不,我检查没有重复的类 – Pravin
