Copilot for .NET is a whole workflow upgrade ⚙️✨
Smarter tests, cleaner refactors, multi‑file reasoning, and real “understand‑my‑solution” energy.
A tight demo with real dev wins.

I've collated 2400+ Microsoft architecture icons and published them for easy access at https://t.co/C1Zv6sIkzn 💙

For every icon, you can:

• Download the scalable SVG file
• Download the PNG of your desired size
• Embed the icon directly into your website or markdown
• Choose a light, dark or transparent background

You can can even compare different icons together and favourite multiple icons for bulk download!

The . “.NET is bloated because of Server GC” meme is over. This is some heroic work done by our GC architect @maoni0 and others on the team.

The backstory is also pretty fun, but I’ll save that for another time 😉.

Howdy everyone! 🙋‍♀️

I just wrote "Deprecated APIs in .NET MAUI 9" to help you identify which APIs to update when migrating to .NET 9. Keep your project up-to-date and optimized! 💚💕

Hope it helps make your transition smoother! 🚀
