The current plan is to continue with EF8 support until we have addressed the remaining missing features (select projections, groupby, aggregations etc) before moving on to EF9.
Is there some specific feature or requirement that you are needing to use EF9 for?
Same problem here… I can’t move to EF Core 9 because of Mongo… I use more providers than Mongo an Mongo it’s preventing from updating the others to EF Core 9
