+By default, a blank user database is created titled "ApplicationDB".  To add additional database objects or data through T-SQL during Codespace configuration, edit the file `.devcontainer/mssql/setup.sql` or place additional `.sql` files in the `.devcontainer/mssql/` folder. *Large numbers of scripts may take a few minutes following container creation to complete, even when the SQL server is available the database(s) may not be available yet.*

[SqlPackage](https://docs.microsoft.com/sql/tools/sqlpackage) is used to deploy a database schema from a data-tier application file (dacpac), allowing you to bring your application's database structures into the dev container easily. *The publish process may take a few minutes following container creation to complete, even when the server is available the database(s) may not be available yet.*
