部署到遠程服務器時出現實體框架架構錯誤

Question

我已經使用EF代碼先創建數據庫。在開發中非常有用。我將它複製到一個Windows Server 2003中，我得到這些錯誤（列在下面）

EF 5，.NET 4.0。

我已經卸載並重新安裝.net 4框架。並在其他機器上測試過。

在我的Windows Server 2008中，它工作正常。在另一個2003盒子上沒有。

爲了將MVC排除在外，我構建了一個簡單的控制檯應用程序，該應用程序列出了數據庫中的一些數據。 - 同樣的錯誤。

我已經在VS 2012中編寫了一切，並在機器上安裝了.net 4.5。我讀過這可能會導致一個問題，所以我重寫了VS 2010中的所有內容，以.net 4爲目標，並手動將引用添加到EF 5/.net4 dll中。同樣的事情，在我的2臺dev的機器的偉大工程，以及2008年的服務器，但不是2003年

錯誤：

這裏的堆棧跟蹤（這是一個MVC應用程序）

Answer 1

我能夠通過更改我的連接字符串來解決這個問題，以便通過在項目中安裝正確的dll來創建新鮮的db。然後我將數據從舊數據庫遷移到新數據庫。

我的假設是，EF 5代碼存儲在數據庫中的一些元數據（雖然我無法驗證這一點）。由於EF代碼首先會在數據庫不存在的情況下創建數據庫/模式，我只是將連接字符串更改爲不存在的數據庫，運行該項目並讓EF構建數據庫，然後從創建的數據庫中遷移現有數據由V.5添加到v.4創建的db。

Answer 2

我更新了.NET Framework到4.5，它工作。
