We just ran into the same issue with a container that was converted from .NET Core v2.2 with EntityFrameworkCore v2.2.6. Now running .NET Core 3 + EFCore v3 and we get this error after deploying a container.

As such it seems something changed. For now I'll add the above fix.

Ouch, can you submit an issue on dotnet/SqlClient to see if there's anything they can do to relax this limitation? Being broken on the docker image by default sounds like a pretty bad experience.
