Worked really well for me, appreciate the tutorial so much!
I expect SQLite to be better and easier for something like a RageMP server (https://www.sqlite.org/whentouse.html), so I mixed your tutorial with this one: https://docs.microsoft.com/en-us/ef/core/get-started/netcore/new-db-sqlite
which also had some better looking syntax for queries and the like which will probably work with MySQL as well. Make sure to mark your x.db as copy if newer, and it should just work!
