"I'll just use github. It's not like I'm supporting Microsoft by using it." -> "I'll just use VS Code" -> (It's okay it's open source) -> "Wow Visual Studio looks good too" -> "I'll just use Windows" -> "Wow look how easy it is to use Azure with Visual Studio" -> "What's Linux?"
Anyone who thinks the former is better than the latter is either a "modern MS" shill or a braindamaged retard. No sane person wants this "modern" UWP idiocy. Since those dipshits are constantly parroting "we want to focus on improvements to this repo", I dare someone to make a PR that just replaces the entire contents with the source of the old calc.exe above. Bonus points for using your real GitHub account or identity.
