部署到远程服务器时出现实体框架架构错误

Question

我已经使用EF代码先创建数据库。在开发中非常有用。我将它复制到一个Windows Server 2003中，我得到这些错误（列在下面）

EF 5，.NET 4.0。

我已经卸载并重新安装.net 4框架。并在其他机器上测试过。

在我的Windows Server 2008中，它工作正常。在另一个2003盒子上没有。

为了将MVC排除在外，我构建了一个简单的控制台应用程序，该应用程序列出了数据库中的一些数据。 - 同样的错误。

我已经在VS 2012中编写了一切，并在机器上安装了.net 4.5。我读过这可能会导致一个问题，所以我重写了VS 2010中的所有内容，以.net 4为目标，并手动将引用添加到EF 5/.net4 dll中。同样的事情，在我的2台dev的机器的伟大工程，以及2008年的服务器，但不是2003年

错误：

Answer 1

我能够通过更改我的连接字符串来解决这个问题，以便通过在项目中安装正确的dll来创建新鲜的db。然后我将数据从旧数据库迁移到新数据库。

我的假设是，EF 5代码存储在数据库中的一些元数据（虽然我无法验证这一点）。由于EF代码首先会在数据库不存在的情况下创建数据库/模式，我只是将连接字符串更改为不存在的数据库，运行该项目并让EF构建数据库，然后从创建的数据库中迁移现有数据由V.5添加到v.4创建的db。

Answer 2

我更新了.NET Framework到4.5，它工作。
