Globalization Invariant Mode is not supported

It isn’t supported for a good technical reason. If you want to use sqlclient in docker you’ll need to make sure you have the icu libraries installed. I don’t know what you’re expecting anyone here to do to change that.

I think the major issue is this one: https://github.com/dotnet/SqlClient/issues/220#issuecomment-535628814 (e.g. it worked for many people without the change in the docker file (e.g. without installing icu))

And that it’s not listed as a breaking change on this page (yet): https://docs.microsoft.com/en-us/ef/core/what-is-new/ef-core-3.0/breaking-changes

Just helping nxtx 😉 And helping nxtx a bit more, the temporary solution isn’t temporary. It’s the (only) permanent solution. Add the 3 lines (or 2 if you remove the comment) just before the ENTRYPOINT part in your docker file and it’ll work just fine.
