    Great to see OpenAPI being even more embraced. It truly is fantastic for multi-team engineering

    Semi auto properties and params collection are long overdue. Great to see them in there.

    System.Text.Json respecting nullability is also great. But may break some things if you didn’t realise you were relying on the old behaviour.

    LoggerMessage source gen using primary constructors fixes a minor pain.

    EF generating SQL at compile time is also pretty sweet. Better query performance from precompiled and better startup performance from not having to precompile at runtime.

    All in all it looks pretty good.
