This is awesome, thank you @alistairmatthews - only a few things to adjust. Also, could we collapse this into a MySQL TOC, and when expend show the links to the EF Core and then non-EF Core docs. We've done this with a few others that are related.

Thanks @IEvangelist. I've modified the TOC to look like the PostgreSQL one. You might want to check it to make sure I've got it right.

It would be good to write a general EntityFramework overview. I wonder if we should have an EF node under integrations and all of the ef integrations there
