connect-to-azure-sql

Connects an application to Azure SQL Database: picks the Microsoft driver for the language, sets encryption and certificate validation, sizes the pool against the worker limit not the session limit, and makes retry part of the first version of the code. Use when a user asks "how do I connect to Azure SQL", "which driver should I use", "what goes in the connection string", "add retry logic", "the connection keeps dropping", "should I set TrustServerCertificate", or "my app times out connecting to Azure". Also use when a first connection to a free or serverless database fails with error 40613, documented resume behaviour, not an outage. Azure SQL Database only, not Azure SQL Managed Instance and not self-managed SQL Server. Driver installation, connection strings and pooling per language belong to connect-from-dotnet, connect-from-python and connect-from-typescript-and-node.
