Editor's note
I kept this issue deliberately mixed, which is how I like it. The Bedrock guardrails piece and the Agent Framework prompt-injection update stood out because AI safety is finally getting practical treatment instead of hand-wavy advice. I also liked the service lifetime explainer and the IAsyncEnumerable article since both hit everyday .NET decisions that affect correctness and performance.
AI safety, Copilot, auth APIs

Your ads ran overnight. Nobody was watching. Except Viktor.
One brand built 30+ landing pages through Viktor without a single developer.
Each page mapped to a specific ad group. All deployed within hours. Viktor wrote the code and shipped every one from a Slack message.
That same team has Viktor monitoring ad accounts across the portfolio and posting performance briefs before the day starts. One colleague. Always on. Across every account.
