Jasen's top three picks

This episode on modernizing .NET libraries should help teams decide what to update, preserve, and simplify without breaking consumers.
- 3 SingleAsync() vs SingleOrDefaultAync() vs FirstAsync() vs FirstOrDefaultAsync() vs FindAync()

The async query comparison article is useful for avoiding subtle data-access mistakes when choosing between Single, First, and Find.
Editor's note
I kept this issue deliberately mixed, with a bit of platform news, fundamentals, and hard-won troubleshooting advice. The Copilot for Azure DevOps piece and the EF concurrency article stood out because they touch real workflows developers run into every day.
