I don’t trust an ORM to automatically reverse a database (or generate a database from POCO types) without at least some configuration - otherwise it can not determine (for example) if two tables, where one’s schema is a subset of another, are meant to be subclasses or not. But anyway - this system feels like when we use T4 to generate types as part of the build process, but more tightly integrated. I wonder if the same could be done for C# using a Roslyn add-in.
