C# 版本支持单声道
C# version support for mono
据我所知，mono 支持 C# 8（以及所有其他以前的版本），但 mono 项目的官方 page
说最新版本是 C# 7，它的实现甚至是部分的，所以发生的事情是单声道的网站不同步，或者我对 C# 的单声道编译器实现有误解？
.NET Core 3.x 和 .NET Standard 2.1 支持 C# 8.0。[1] Mono 6.4+ has partial support for the latter in that it apparently can load and run .NET Standard 2.1 code without an issue, but since a library targeting Standard 2.1 can normally only be referenced by other 2.1 libraries or a .NET Core 3+ executable, writing an application for Mono that can actually utilize .NET Standard 2.1 requires you to invoke the C# compiler manually.[2]
我的 个人 猜测是，由于对 .NET Standard 2.1（以及扩展 C# 8）的支持非常有限，他们没有费心将它包含在官方文档中.

2 Clarify how to use .NET Standard 2.1 from Mono · Issue #1689 · dotnet/standard · GitHub
作为旁注，他们的 Compatibility page seems to indicate that C# 7 is fully supported. If you'd like a proper answer as to why the two pages differ, I suggest you ask a question on their Issue tracker.
