I'm working on a project which at the moment is not being used for any commercial purposes, and I'm managing the data by using a SQL Server Database.
I read here that I should pay for it if I ever wanted to upload this database in a productive environment. So my question is: Is there any alternative to keep using it for free? If there's not, could I use the Express edition until I have 10GB of data?
The thing is I'm using EF Core to connect to the database, so I'm pretty attached to SQL Server.
