xAI just announced that Grok 4.7 so I wanted to try their model with C#. This isn’t another incremental update—it’s a model specifically architected for advanced reasoning, long-horizon problem solving, software engineering, and agentic workflows. For .NET developers building enterprise applications with AI capabilities, here’s what actually matters and how to put it to work. […]

There are a lot of AI model announcements these days, but every now and then one lands that feels immediately practical. Claude Haiku 5.5 is one of those releases.

The examples were deliberately substantial: bug investigations, BI recommendations, template-based reports, approval-gated record updates, and long-document synthesis. Now there is a different question: Can you afford to do that every […]
In my Claude Opus 5.5 for C# developers post I called Opus 5.5 from my own code: the Anthropic.Foundry SDK, Entra ID, and the effort parameter. This time the code calling Opus 5.5 isn’t mine. It’s Claude Code, running in my terminal and in VS Code, pointed at my Foundry resource. Microsoft already has a […]
Anthropic’s newest model, Claude Opus 5.5, just landed — meaning if you’re already building with Claude, you can call Anthropic’s most capable coding-and-reasoning model with a resource API key. Here’s what’s actually new, and how it looks from C#. What Actually Shipped A few facts worth knowing before you touch any code: 40% cheaper than […]
