Editor's note
I put together a mixed lineup this time: production-focused framework updates, data access changes, and a few hands-on optimization pieces. The .NET 10 ASP.NET Core article and the EF Core 10 join write-up stand out because they both affect real application code, not just release notes. I also liked the Redis and cache items for teams trying to squeeze more throughput out of existing systems.
