部署到微軟Azure網站Asp.net MVC網站拋出錯誤

Question

我使用的Visual Studio 2015更新3 我ASP.NET MVC 4網站。目標框架：.NET Framework 4.5。該網站有自己的數據庫。該網站在本地工作並與數據庫交互（(LocalDb)\v11.0）。

然後我用發佈按鈕部署現場Azure網站通過VS。 Web App已成功發佈。但我無法在瀏覽器中打開它。我收到以下錯誤的瀏覽器：

Server Error in '/' Application.

這裏是我的數據庫連接字符串中Web.config：

<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=OnlineAuctionDb;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\OnlineAuctionDb.mdf" providerName="System.Data.SqlClient"/> 

我上傳整個Web.config fi le到DropBox

這是數據庫的問題嗎？我已經發布了整個網站，使用VS中的發佈按鈕。但可能數據庫沒有附加到雲網絡應用程序？我不確定。如果問題在於缺少數據庫，我如何發佈與網站相關的數據庫以便它們一起工作？

Answer 1

問題肯定是網站無法找到或與數據庫進行通信。有幾種方法可以做到這一點，但你需要弄清楚要如何託管數據庫 - 它看起來像你使用SQL，所以你的選擇是：

1. 的SQL Express /的LocalDB上例如，您的網站上
2. Azure的SQL數據庫（將在Azure和訪問您的網站託管）
3. SQL Server中的虛擬機託管在Azure中
4. 另一個SQL數據庫的其它託管（處所也許）並運行可以通過混合連接來訪問

我建議使用選項2，因爲它爲您提供了可隨您的應用程序擴展的開箱即用管理解決方案，但是可以通過網絡尋址，因此您的Web應用程序的多個實例可以共享它，並自動備份等。等等。

也許分享一些更多的信息，你已經得到了什麼或者你想要達到什麼？
