Azure Copilot, async, and security
Issue #140 covers Copilot for Azure DevOps, async and threading patterns, HttpClient and GC deep dives, plus security and EF concurrency tips.
Jasen's top three picks
- 1 GitHub Copilot for Azure DevOps users
Microsoft Dev Blogs
Copilot arrives for Azure DevOps users, which is a practical sign that AI help is moving deeper into everyday delivery workflows.
- 2 449: Modernizing .NET Libraries
Merge Conflict
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()
Medium
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.
