Because cross-compiling binaries for Windows is easier than building natively
I want Microsoft to do better, want Windows to be a decent development platform-and yet, I constantly see Microsoft playing the open source game: advertising how open-source and developer friendly they are - only to crush developers under the heel of the corporate behemoth's boot.
The people who work at Microsoft are amazing, kind, talented individuals. This is aimed at the company's leadership, who I feel has on many occasions crushed myself and other developers under. It's a plea for help.
It's never a good sign if people developing for your platform are not developing on that platform.
