The closest I got was by just using avalonia. I had to use winforms for my uni and convincing my teachers to allow my team to use avalonia was not easy. Avalonia is not even remotely similar to winforms. You can try setting up a VM, but I understand that it is not a real solution. I found some docs for an old version of mono which referenced some of the winforms API, but I had no luck running it.
I won’t be pirating manga if I can actually pay for them. Some apps exist, like mangaplus, but they pale in comparison to something like tachiyomi. And then there is webtoon which shoves an ad in my face even though I purchase content weekly to read. And webnovel is atrocious with how I have to wait 5 seconds for an ad before they show me yet another ad every time I open the app. I just use koreader now for novels. I do buy physical volumes to show some support back. But a Korean series that I am reading does not have a novel published overseas, kind of a bummer.
