  • Revisiting WASM for F#
    I would also say that IF blazor worked on a browser plugin like silverlight did, today that's not the case it is built on the webassembly standard which and it is being adopted in the browsers which means once it gets on the web, it is unlikely to ever go out again. Even if Microsoft themselves leave Blazor today, it can still work, the burden of creating a fork and keeping blazor alive will certainly be big but... - Source: dev.to / 5 months ago
  • Seeking Advice on Product Positioning for new .NET-based SDK/Framework
    Under the Hood: Technically, XR# integrates Three.js, A-Frame.js, and the Microsoft .NET to WASM compiler (like in Blazor). It’s built on our decade-long experience with OpenSilver, a contemporary Silverlight alternative. Source: 8 months ago
  • WASI: A New Kind of System Interface
    Nah, I appreciate the wonderfull work of those WebAssembly people that allowed me to have Java applets, Flash and Silverligh running again in the browser. https://leaningtech.com/cheerpj/ https://leaningtech.com/cheerpx-for-flash/ https://opensilver.net/ Thanks for making the revenge of plugins a reality. - Source: Hacker News / about 2 years ago
  • 20 Years of .NET
    Now there is a company making Silverlight work on top of WebAssembly. https://opensilver.net/. - Source: Hacker News / about 2 years ago
  • Prime Video Uses WebAssembly
    It will definitly be the new common, by killing Flash et all without comparable tooling, while at the same time offering WASM, it was only a matter of time until we had the revenge of plugins. Basically 10 years wasting time to come full circle. https://leaningtech.com/cheerpj https://leaningtech.com/cheerpx-for-flash/ https://opensilver.net/ All of the three major ones are now back, but it is ok, WASM is great! - Source: Hacker News / over 2 years ago

  • .NET on Linux: What a Contrast
    Yes, but the portable GUI frameworks by Microsoft themselves are generally not very good, and they tend to be abandoned after a couple of years. Avalonia is developed outside of the Microsoft corporate madness and seems to be slowly becoming the defacto cross-platform framework because it is expected to last a bit longer than a manager's attention span: https://avaloniaui.net/. - Source: Hacker News / 3 months ago
  • Course using F#: Write your own tiny programming system(s)
    You should be able to use Avalonia[1] as an alternative GUI layer on Windows, Linux, macOS, iOS and Android. There is a beautiful Avalonia.FuncUI[2] and Avalonia.FuncUI.Elmish[3] which is an implementation of Elmish[4] (based of the Elm language[4]) for F#.

  • Why Is the Front End Stack So Complicated?
    To bad Microsoft refuse to work on proper cross platform WPF support. I've tried Avalonia UI[0], but it's just not the same. For instance the lack of a proper out-of-the-box virtualized list. [0] https://avaloniaui.net/. - Source: Hacker News / 7 months ago
  • One Game, by One Man, on Six Platforms: The Good, the Bad and the Ugly
    For desktop, Avalonia, hands down. https://avaloniaui.net/ Open source, powered by Skia, backed by JetBrains, and quite battle-tested at this point for small to medium-sized apps. In theory perfectly capable for enterprise as well, since it's basically a spiritual successor to WPF, which has been an industry standard for about 15 years. They're diving into mobile and WASM well, but that's more of a recent effort... - Source: Hacker News / 7 months ago
