我用自己的Visual Studio在我自己的电脑上创建了一个Visual Studio 2013应用程序。该应用程序正处于测试阶段，我必须将其发送给我的工作。问题，为什么我启动.exe，我有错误要运行此应用程序，您首先必须安装以下版本的.NET Framework之一：.NETFramework，Version = v4.5兼容性实体框架通过降级/网络框架4.5到3.5
如果我可以安装框架，这不会有问题，但我工作的企业不会更新它。 Thay站在3.5 SP1中。
我有（我认为），成功地解决有关的DataGrid（Retromigration 4.5 to 3.5 .net framework for c# application）
我的第一个问题，但现在，我有很多的警告和错误，或多或少都对同一件事情，实体框架。
这是他们的3：

等等等等等等
我知道实体框架3.5已经存在，那么我该怎么做才能让它再次合作？
