Is “N+1 Queries” Still A Performance Issue In Entity Framework Core 3?

In a previous post we saw that EF 2.1 is highly susceptible to the N+1 queries problem.
After the release of a new version of Entity Framework Core (EF) the first question coming to mind is: “Is it still a big issue in EF 3.1?” And if the answer is no, is there anything else we have to be aware of?
