Today we are announcing the retirement of the Visual Studio for Mac IDE. Visual Studio for Mac 17.6 will continue to be supported for another 12 months, until August 31st, 2024, with servicing updates for security issues and updated platforms from Apple.
I really like the idea of having a web UI for its portability and richness (esp thanks to CSS being so close to consistent across all platforms). But I have a metric tonne of business logic and ZKE code in C#/.Net running on Mac/iOS. From your prompt, I did just find Electron.Net, so perhaps there is hope.
And, AFAICT, electron can’t be used for iOS apps on the App Store (am I still wrong about that??)
Plus (personal bent) I did a ton of JavaScript years ago when truthiness and indeterminate behaviour was rampant back in ES5 days. I’m a purist and found it a little ugly, but incredibly fast. Then I found dart which compiled to JS, and I decided that JS made a better assembly language than a usable language. Sadly dart has remained a minor player. JS has moved on and I see lots of the old ugliness (like iterating through properties, exceptions and a sync) has gone away. ES13 looks pretty good, although I haven’t played with it yet.
Have you looked into Flutter? It uses Dart and can compile to native apps for android, ios, windows, Mac, Linux, and web.
