dev-container-templates

Sets up local development from the Azure SQL Database dev container templates in microsoft/azuresql-devcontainers (.NET, .NET Aspire, Node.js, Python), each with a sample database and schema loaded. Use for "start from the Azure SQL Database dev container template", "which Azure SQL Database devcontainer should I pick", or "add a dev container with a database already in it", and for what these templates do: an empty database, a schema project that never deploys, a saved profile prompting for a password, a database at localhost not a service name, a vector index refused, a port on the app service refused, or the local database in a template not behaving the way the Azure SQL Database documentation describes, because it is SQL Server. Covers the SQL Database project whose target platform, not the engine, decides what Azure SQL Database accepts, and the create-time build and publish.
