使用 SQL Azure 为 db 和 Azure Web 托管构建应用程序，首先在云中使用 TFS .NET 4.5 EntityFramework 代码。
在对防火墙进行了一些调整之后，我能够成功地将我的本地计算机连接到 Azure 数据库，并且一切正常。
connectionString="Server=tcp:wwww.database.windows.net,1433;Database=MyDB;UserID=UserName@wwww;Password=Pwd;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;" providerName="System.Data.SqlClient"
我将 Azure 面板配置为允许其他 azure 服务连接，成功签入我的代码，构建成功并自动神奇地部署到我的 web Azure 托管网站。然后我会看到一个黄色的死亡屏幕。对我可能遗漏的东西有什么想法吗？
