As far as I know they have been using .NET Core (or just EF Core? would be weird to go EF Core + .NET Framework, I guess?) on prod in 2018:

So maybe they used some things on Linux and some things on Windows - those that couldnt be ported to .NET Core back in the days

They're using .NET Core, and I think even .NET 5 in the meantime though I couldn't find a clear confirmation for that. But they're still on Windows, looking at Linux and containers for potentially in the future.
