Note: This issue is tracking a specific aspect of using EF Core with database views. See #827 for an overview of the areas where EF Core interacts with database views. The completion of this feature does not mean that every aspect of database view support has been implemented.

See also #5719, which is about support for tables without keys.

Part of #830. At the moment we generate code only from tables, not views. Need to include views but may have to consider what we want to use as the primary key.
