Question

我在Azure上创建了一个数据库我也可以通过设置防火墙等来从本地服务器访问Azure Sql数据库

我注意到当我执行表模式更改时，例如创建新表或向现有表添加新列时，更改不会反映在Azure应用程序上（尽管我可以在Azure SQL上看到最新的表更改数据库查询编辑器）

我尝试使用默认的TODO表修改Azure提供的示例TODO应用。

从Azure下载应用程序并运行它后，通过从TODO表加载适当的数据，应用程序运行没有任何问题。

但是当我向现有的TODO表添加新的列/重命名列时，更改DOT文件以在api服务中添加新列并发布该服务。 APP停止显示连接错误的数据......

根据错误消息，您正在为Azure移动应用程序使用C＃后端。要添加新表，您需要定义表的模型并为其创建表控制器。要编辑列，您可以编辑表模型。在将后端发布到azure之前，您需要实现代码优先迁移，您可以通过add-migration手动创建迁移文件，并利用命令update-database来应用现有迁移。此外，您可以启用自动代码首次迁移。更多细节，你可以参考adrian hall的书Implementing Table Controllers。此外，您还可以查看Handling Publish Failures。
