Electron app
Shame. I do my best to avoid the resource bloat of electron apps whenever possible.
I mean, when my own iron - dual 12-core 24-thread Xeon E5, 128Gb RAM - sees non-trivial impacts from just two or three Electron apps, I do my best to nip that in the bud by avoiding all that crap.
What’s so hard about building a traditional app? With DotNet you could build a single program for all three platforms, and you could bundle DotNet up into that app such that it doesn’t even need a separately-installed sandbox like Java does.
From what I have seen, AvaloniaUI is getting really close to being the ideal framework for cross-platform desktop use. It has become very polished over the last two years.
MAUI on the other hand, has been falling flat on its face on desktop because it is geared much more towards mobile.
