How stable is .NET 10 RC1 for production use, especially with new features like Post-Quantum Cryptography and MAUI updates? Moreover if someone is looking great deals on software and more I recommend using OkCodePromo.fr.
Lets hope it gets more pythonic
return ip_map.get(ip, f”{ip} unknown”)
instead of
return ipmap.TryGetValue(ip, out string? name) ? name : $”{ip} unknown”;
I mean C# shouldnt try to compete against java anymore.. that’s so 80’s.. 90s.. 2010..
Why shouldn’t we have vs2026 on linux and macos? Windows is a pure garbage and me and many of my friends do not prefer develop on it but Visual Studio has good things to use. Why It should be bounded to windows (the garbage)?
Calling an entire platform “garbage” is disrespectful and uncalled for. I’ve had my own struggles with macOS (I mainly use Windows and Debian), but I don’t resort to extreme remarks like this. Plenty of developers work across different platforms, and if you can’t show basic respect for that, you probably don’t belong in the dev communities. Be professional, be constructive, and respect the tools others choose.
This “pure garbage” has over billion installations worldwide and represents more then 70% market share.
Nice to see RC1 with a GoLive! Alongside VS 2026 Insiders and VS Code, I assume it runs under VS2022 Preview?
…actually it looks from the .NET downloads page, Visual Studio 2026 (v18.0 Preview 1) is mandatory, so it’s time to uninstall VS2022 Preview. But will the final release work under VS2022 (non preview) given VS 2026 is just at Preview 1?
It appears RC1 (.NET 10.0.0-rc.1.25451.107) over-installs atop Preview 7 and does indeed run under VS2022 17.14.13 Preview 1.0 as expected.
