The latest hotfix build for v5.6 now contains the EF Core 3.0 and .NET Standard 2.1 support for EF 6, EF Core 2.2+ and LLBLGen Pro Runtime Framework.
Please use the locally installed documentation, as the online docs haven't been updated yet as it's not an RTM release yet. (likely in a week or so if no problems arise).
We implemented TVF support in EF Core 3 as a new feature for EF Core, please see the docs how to use that.
