Learn how Visual Studio enables Segment Heap by default for new C++ projects and how to adopt and verify it in existing builds.

Use exponential backoff and circuit breaker patterns in Azure Functions with Service Bus SDK bindings. Control retry storms, protect dependencies, and degrade gracefully under transient failures.

You’ve probably experienced both of these, perhaps at the same time. First, that desire to let an agent get at your data. It’s driven by simplification and better experiences for the user and for you: fewer screens, fewer queries, fewer reports, and less code overall. Second, and...

Building powerful AI agents is only half the story, running them safely in production is the real challenge. As customers adopt Microsoft Agent Framework for agent orchestration, a clear need has emerged for robust, built-in governance. In this post, Imran Siddique from the AGT team walks...

Network security has a funny way of showing up late. You start with a web app, an API, storage, and Key Vault. The app works. The demo works. Everyone is happy. Then the production checklist shows up: Can storage and secrets be taken off the public internet? Can this app run inside our...
