我是编程新手，但并不是Linux新手。 我最近在C＃中开始了一个编程类，我们使用Visual Studio 2015编写应用程序，因此使用MSbuild编译它们。 然而，在家里，我想用mono来编译所有的东西，但是当我尝试的时候，我得到了一些错误，并拒绝编译。 这是我运行的程序：
$ xbuild Dice_Game.sln 这是stderr：

看来我可以做这个工作…我只是没有足够的经验，使单声道工作。 任何帮助，将不胜感激。
请将您的项目的目标框架更改为.NET 4.5。
目前Mono不支持.NET 4.5.1及以上版本。
我的头发在这拉了一半。 有很多方法来安装单声道，有些会安装一个过时的版本。 我记得以下一些关于VS Code和Omnisharp的说明。
因此，要获得最新的安装，请按照单声道的下载页面上的说明设置apt源，然后执行以下操作：
sudo apt install --reinstall mono-complete sudo apt upgrade
xbuild开始工作，但表示它已被弃用，所以使用msbuild 。
