It depends on your Linux distro, it's at least 300MB+. The packages are especially sprawling, installing mono from the official repository is 100+ individual packages. It involves running various additional tasks that are totally unique to mono. Regenerating certificates, recompiling itself (despite being a binary distribution), thousands of random bullshit non-code files. It's like it wants to be it's own little operating system unto itself. Nevermind WinForms is unsupported and extremely buggy.How big is it?
.net core is like 600MB
Mono works, but it always feels like you're in edge-case city. It's like the developer needs to specifically make sure everything is kosher in Mono.
