When you installed it, you probably used

当你安装它时，你可能会使用它

sudo apt-get install mono-complete

In my case, this installed Mono 3.2.8 which is evidently lower than 3.10.0. I couldn't manage to upgrade my Mono installation to a more recent version until I found this workaround:

在我的例子中，这安装了Mono 3.2.8，显然低于3.10.0。在找到此解决方法之前，我无法将Mono安装升级到更新版本：

sudo apt-get install mono-devel

This will install the developer package which, as of yesterday, comes with Mono 4.0.1. This will replace your existing Mono 3.2.8 installation with the newest version and when you restart VS Code, you'll notice that the error is gone and everything seems to work perfectly. Likewise, executing a program will also no longer have TypeLoadExceptions.

这将安装开发人员包，截至昨天，它配备了Mono 4.0.1。这将用最新版本替换您现有的Mono 3.2.8安装，当您重新启动VS Code时，您会注意到错误已经消失，一切似乎都完美无缺。同样，执行程序也将不再具有TypeLoadExceptions。

I blogged about this in more detail here.
