CoreWiki throws Errors if only dotnet core 2.2 is installed

If you only have .Net Core 2.2 installed, CoreWiki will throw a lot of errors when trying to compile. There's no clear documentation online about how safe it is to install .Net Core 2.1 on top of .Net Core 2.2 (which is what I ended up doing - it worked).

Probable long term solution is to upgrade CoreWIki to .Net Core 2.2.
