Someone else signed their messages exactly like that. So this is just your new account, old one likely banned, I can see why.
Still continuing spying other people instead of contributing something useful for the common good? Ok, you have once been in my Ignore List, then I had removed you, but as we can see you deserve to land again in my Ignore List. Bye-bye, SH!
Maybe you were a developer but probably over 1 or 2 decades ago. There is no way you currently deal with coding issues judging from the nonsense you published. Fyi, check out Net 6 (or called dot net core). It runs on all major operating systems natively. That means C# or even VB runs on Mac or Linux natively.
Well get this: the world's largest software repository github is owned by Microsoft. This must sting ;-)
From what I understand WinForms isn't available on Linux in any usable, relatively bug-free way. You can still write non-GUI apps but that's not a full implementation. Meanwhile in other languages you can go with Qt which is truly cross-platform with only the smallest of tweaks. Is my assessment wrong?
You are right, but Winforms is mostly out of the picture, that is a technology that was oriented to Win OS only. These days you can use https://devblogs.microsoft.com/dotnet/introducing-net-multi-platform-app-ui/
