Question

我有一个发布到Microsoft Azure的Web应用程序。有两个数据库，都托管在Azure中的SQL Server上。一个处理身份验证的数据库工作正常，我可以登录/查看与其他数据库无关的页面。当我尝试执行访问其他数据库的操作时，我在本文的底部收到错误。

它必须是Azure中的东西。当我在本地运行应用程序时，它工作正常，即使它仍然访问相同的Azure托管数据库。以下是我正在使用的连接字符串（我已经更改了一些敏感信息），它们在本地工作正常：

<connectionStrings>
<add name="IdentityConnection" connectionString="Server=tcp:{server}.database.windows.net,1433;Database=identity; ID={User};Password={pw};Trusted_Connection=False;Encrypt=True;Connection Timeout=30;"
  providerName="System.Data.SqlClient" />
<add name="DataConnection" connectionString="Server=tcp:{server}.database.windows.net,1433;Database=Data;User ID={User};Password={pw};Trusted_Connection=False;Encrypt=True;Connection Timeout=30;" />

Answer 1

嗯，事实证明，从Visual Studio发布对web.config的更改实际上是一个问题。尽管整个项目的几个整体发布和个人单独发布到web.config，但是Azure中托管的web.config的版本保持不变，仍然在连接字符串中引用了本地数据库。通过服务器资源管理器中的网站文件直接编辑web.config允许我解决问题。虽然是讽刺性的。

在管理门户中，您是否为Azure服务启用了SQL Azure服务器防火墙？ http://azure.microsoft.com/en-us/documentation/articles/sql-database-get-started/#ConfigFirewall
