答案

您需要创建一个Azure API应用. Xamarin应用程序将使用此REST API与数据库进行交互.

Answer

You'll need to create an Azure API App. The Xamarin app will use this REST API to interact with the database.

永远不要使用数据库的connection string将移动应用程序直接连接到远程数据库，因为这样可能会破坏数据库.例如，如果移动应用程序用户的互联网连接较差，并且他们直接连接到数据库，则该应用程序可能无法完成执行数据库查询. API将确保不会因互联网连接不佳而导致数据库损坏.

Never connect a mobile app directly to a remote database using the database's connection string, because this opens up the potential for database corruption. For example, if the mobile app user has a poor internet connection, and they are connecting directly to the database, the app may not be able to finish executing a database query. An API will ensure that no database corruption happens due to a poor internet connection.

我有一个示例应用程序和一个演练，其中显示了如何创建Azure API应用程序，如何将其连接到Azure SQL数据库以及如何使移动应用程序与REST API通信.

I have a sample app and a walkthrough here that shows how to create an Azure API App, connect it to an Azure SQL Database and how to have the mobile app communicate with the REST API.
