部署到远程服务器时的实体框架模式错误

我首先使用EF代码创建数据库。在开发中工作得很好。我将它复制到Windows Server 2003框中，我得到这些错误（如下所列）

EF 5，.NET 4.0。

我已经卸载并重新安装了.net 4框架。以及在其他机器上测试过。

在我的Windows Server 2008上，它运行正常。在另一个2003年的盒子上它没有。

为了使MVC脱离等式，我构建了一个简单的控制台应用程序，列出了数据库中的一些数据。 - 那里有同样的错误。

我已经在VS 2012中编写了所有内容，并在机器上安装了.net 4.5。我读到这可能会导致问题，所以我在VS 2010中重新编写了针对.net 4的所有内容，并手动添加了对EF 5 / .net4 dll的引用。同样的事情，在我的2台开发机器和2008服务器上运行良好，但不是2003年。

错误：

这是堆栈跟踪（它是一个MVC应用程序）

2 个答案:

答案 0 :(得分：3)

我能够通过更改我的连接字符串来解决这个问题，让ef在项目中安装正确的dll时创建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代码在DB中存储了一些元数据（尽管我无法验证这一点）。如果数据库不存在，EF代码首先会创建db / schema，我只是将连接字符串更改为不存在的数据库，运行项目并让EF构建数据库，然后从创建的数据库迁移现有数据通过V.5到v.4创建的数据库。

答案 1 :(得分：0)

我将.NET Framework更新为4.5并且运行良好。
