What to read about the internals of EntityFramework Core?

Question

.NET

All articles and documentation for EF Core contain only examples of how to work with EF core (CRUD, change tracking, migrations, transactions, etc.) but almost nowhere is it mentioned how it works inside EF Core. For example, how EF Core tracks changes in entities or how it builds queries in SQL. What can be read on this topic? I would like to at least superficially imagine what is happening there in order to write more meaningful code.
