    WPF is not the best example of open source, as some components are still closed source. Though it only runs on Windows, a closed source operating system, so perhaps that is not so important.

    That said, there are cross platform, open source .NET UI frameworks out there, including one that is inspired by WPF:

  • Project mention: The Rise and Fall of the LAN Party | news.ycombinator.com | 2024-04-24

    Recently, my friends and I recreated our old LAN parties. Went up to a cabin in the woods, brought some cheap network switches, and had everyone install OpenRA (https://www.openra.net/, open red alert), and had a blast, even with everyone on laptops (mac/win). You can still do this in 2024 and it's worth it!

  • Project mention: Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones? | news.ycombinator.com | 2024-05-06

    As someone who writes software for moderately boring business operations, I've been wondering making terminal-based apps with lots of keyboard shortcuts would lead to a more productive end user than writing a web app.

    It looks like the port was compiled with a binary SkiaSharp [0] since that requires Google tooling to build. Interesting to see the committer allowing this. Apparently it is not the first time.
