This sample shows a tiny ORM with simple POCOs, a lightweight Include for eager loading, and full CancellationToken propagation.

cd Demo.App
dotnet run

Press Ctrl+C to cancel while running; the app will stop gracefully.

• Simple POCOs: Blog, Post with [Table], [Key], [ForeignKey], [InverseProperty].
• Include for both collections and references (extra queries per entity).
• Cancellation support across: opening connection, executing commands, include loading, seeding, and saving.

Replace Microsoft.Data.Sqlite with Microsoft.Data.SqlClient and change identity retrieval in SqlBuilder.Insert to SELECT SCOPE_IDENTITY();.
