Question

以下是我的web.config文件。我目前正在学习如何自己部署网站，因为我没有找到任何资源来学习如何使用连接到azure数据库的ADO.NET（实体框架/使用数据库模型）来部署网站。我创建了一个测试页面，它只是从特定的表中获取所有记录。完美的开发工作。我只是上传了web.config，default.aspx，default.aspx.cs和bin文件夹。我正在使用去爸爸。不幸的是，我收到一个错误，告诉我我没有连接到数据库！任何人都可以帮助我吗?? !!!

以下是我的错误和堆栈跟踪建立与SQL Server的连接时发生与网络相关或特定于实例的错误。服务器未找到或无法访问。验证实例名称是否正确，以及SQL Server是否配置为允许远程连接。（提供者：命名管道提供程序，错误：40 - 无法打开与SQL Server的连接）
