Microsoft.Extensions work planned for .NET 7

[maryamariyan]

This issue captures the planned work for .NET 7. This list is expected to change throughout the release cycle according to ongoing planning and discussions, with possible additions and subtractions to the scope.

Summary

For .NET 7 we are prioritizing the work to improve code reliability and minimize the number of high-impact bugs in the codebase. There's also some bottom up planned community requested feature requests available in the list.

Hi @maryamariyan - I'm happy to continue with #36390

Do we know yet what needs to be different this time around? We reached an impasse last time as we didn't want to change the declared type at runtime (IEnumerable<T> to IList<T>).

I'm please to hear that it's being considered again though, as I think this issue will be more and prevalent as projects are switched over to have Nullable Reference Types switched on: #52514 (comment)
