【问题讨论】：

您能否使用 Sql Server Management Studio 连接到您的 Azure 数据库？
它在本地连接到 SQL Azure 或连接到本地数据库上工作正常？如果是后者，请尝试让您的本地开发代码连接到实时 SQL（可能需要添加您的 IP），因为这比每次部署都容易
您是否使用通过在 Azure 门户中打开 SQL 数据库并单击“显示数据库连接字符串”找到的连接字符串。还要在应用程序设置下检查您的应用程序是否使用了此连接字符串。

【解决方案1】：

尝试关闭连接池，在连接字符串中设置Pooling=False。

有效答案。免得我头疼。

【解决方案2】：

如果没有看到您的实际连接字符串，我无法完全肯定地说；但是，从堆栈跟踪错误的外观来看，它表明您的连接字符串正在使用：

providerName="System.Data.EntityClient"

尝试在您的连接字符串中添加：

providerName="System.Data.SqlClient"
