迁移到 EntityFramework 和 VS 2013 后，我无法更新或删除资源。

有什么想法吗？

感谢您的帮助。

最佳答案

万一有人想尝试这个解决方案......我遇到了同样的问题。如果我将分离的实体附加到上下文然后尝试更新/删除它，似乎会出现此错误。

Entity entity; //detached

context.AttachTo("entitySetName", entity);
context.DeleteObject(entity);
context.SaveChanges(); //exception

这对我有用。

//get entity from context instead of attaching the "old" one
var newEntity = ctx.Table.Where(w => w.ID == Entity.ID).FirstOrDefault();

context.DeleteObject(newEntity);
context.SaveChanges(); //works
