AI Workflows, Resilient APIs and .NET Performance
This edition covers Visual Studio Git workflows, crash-safe workers, MCP servers, rate-limit tests, and .NET 10 and 11 measurement.
Jasen's top three picks
- 1 Visual Studio October Update – Compare Commits to Your Code, Resolve Conflicts in Bulk, Keep Coding
Microsoft Dev Blogs
Useful source-control improvements for reviewing local changes against a prior commit and handling a batch of conflicts without leaving the IDE.
- 2 How to Use Azure OpenAI with the GitHub Copilot SDK in a C# Application
C# Corner
A practical integration walkthrough, with the important configuration and credential-handling considerations included.
- 3 How to Resume a File Processing Job After a Worker Crashes
C# Corner
Checkpointing, leases, and idempotency are the foundations of restartable workers; this is a worthwhile production-readiness checklist.
Editor's note
I’ve curated another deliberately mixed set of practical .NET reading, from AI integration to production reliability. The HttpClient resilience guide is useful for validating real retry behavior, while the crash-recovery worker pieces focus on the idempotency details that prevent expensive duplicate work.
