🎨 Text-to-Image in .NET — FLUX.2 Pro in the Foundry and Stable Diffusion on Your Machine Hi 👋 These days Microsoft announced FLUX.2 Flex on Microsoft Foundry, I immediately thought: "I need to wrap this for .NET developers." So I setup a SQUAD team and I did it. And then I thought: "Wait — I have a couple of Test-to-Image local pet projects, what if my SQUAD also help to polish and publish this? Same interface, and of course let's make it Microsoft Extensions for AI compatible"

🤖🗣️ Local AI Voices in .NET — VibeVoice & Qwen TTS Hi! Let’s look at these 2 code snippets… what’s behind them? 🧠 Snippet 1 — VibeVoice (Native TTS in .NET) using ElBruno.VibeVoiceTTS; using var tts = new VibeVoiceSynthesizer(); await tts.EnsureModelAvailableAsync(); // auto-download model if needed float[] audio = await tts.GenerateAudioAsync("Hello! Welcome to VibeVoiceTTS.", "Carter"); tts.SaveWav("output.wav", audio); This generates a WAV file from text using the VibeVoice-Realtime-0.5B model, running locally via ONNX.

🤖🗣️ Local AI Voices in .NET — VibeVoice & Qwen TTS

You can now generate natural AI voices locally in pure C# using ONNX and VibeVoice or Qwen TTS. Just a few lines of .NET code and you’re speaking.
If you're exploring local AI, this is a great place to start 👇

What Building AI Agents in .NET Taught Me in 2025 Hi! In 2025, I built more AI agents in .NET than I expected. Some were demos.Some were prototypes.Some (few) actually made it to production. And while models kept getting better every month, the hardest problems I ran into had very little to do with AI itself. They were engineering problems. Here are a few lessons I wish I had internalized earlier.

Claude in Azure with .NET – Anthropic Claude + Microsoft Extensions.AI (MEAI) 💥 Hi👋Great news for .NET developers: Anthropic’s Claude models (Claude Sonnet 4.5, Haiku 4.5, Opus 4.1) are now available in Microsoft Foundry (public preview anthropic.com). This makes Azure the only cloud platform providing access to both OpenAI’s GPT and Anthropic’s Claude frontier models side-by-side (azure.microsoft.com). In practical terms, you can deploy a Claude model to your Microsoft Foundry resource and consume it through Azure’s familiar endpoints and billing system, just like an Azure OpenAI model.

Claude is now in Azure! 🤯
I built a .NET client to use Anthropic's models in C# with MEAI and Agent Framework. Stream responses, run Claude in agents, and more 💥 Includes code, NuGet, and a demo video. #dotnet #azure #ai #claude #anthropic #meai #elbruno

Introducing the Microsoft Agent Framework – A Dev-Friendly Recap Hi there! 👋 If you've been keeping an eye on the AI developer world, you might have heard about the Microsoft Agent Framework. This is a brand-new (as of late 2025) open-source SDK and runtime from Microsoft that makes it much easier to build and orchestrate AI agents – including scenarios with multiple agents working together. In this post, I'll give you a friendly rundown of what the Agent Framework is, why it’s exciting, and how you can start tinkering with it in C#.

🚀 Just published a hands-on recap of the Microsoft Agent Framework!
