You use ASP.NET Core MVC with ADO.NET to develop an application. You implement database sharding for the application by using Azure SQL Database. You establish communication links between the shard databases.
You need to implement a strategy that allows a group of operations that are performed on multiple Azure databases to be rolled back on all databases if any of the operations fail.
Solution:
* In the .NET method, define a new transaction in a using block.
* Within the using block, establish connections to each Azure SQL Database instance.
* Run the SQL operations on each connection. If no exception occurs, commit the transaction.
