I can now use Mono to launch Minecraft after applying these little modifications.
Thank you for reviewing my code!

The CI build failed because I am using NuGet package DotNetZip to deal with zip files.

I'm the initial developer. There is a reason why this library doesn't support *nix.

We all want to embrace the latest technology such as .net core and the outdated framework is undoubtedly annoying when developing. However, you will find that its framework version is "v4.0". It's the last version that is supported on Windows XP and Supporting Windows XP is actually an important feature. Although Windows XP's market share in China has decreased a lot in recent years, there are still many Windows 7 machines in China that is "optimized", which makes an upgrading .net version very difficult. The reason to avoid NuGet is the objective to produce a single binary. To sum up, nearly everything that outdated is to meet the fundamental realities of the country.
