MVC 会话序列化错误。无法找到程序集 'EntityFrameworkDynamicProxies

Question

我有一个 mvc 商务项目。我使用会话进行用户登录。例如我在这样的会话中使用会员信息。Ofc 会话不为空。

Member member=Session["MemberSuccess"] as Member

还因为共享主机的池时间，我使用 sql 状态会话。它在本地主机上运行良好。但是当我将它上传到服务器时，它会给我一个这样的错误；

Unable to find assembly 'EntityFrameworkDynamicProxies-DataLayer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

我不知道是否有任何相关性，但我的服务器信任级别已满。我使用实体框架。我将 edmx 文件保存在一个单独的类库中。我也试过 在 .tt 文件下的类中添加 [Serializable] 属性。

这是堆栈跟踪

尝试在您的 DbContext 类中禁用代理创建：

context.Configuration.ProxyCreationEnabled = false;
