Notes...

NET Core on Linux can be checked in various methods that I have found. I think dotnet --list-runtimes will be something we need to do in order to validate it is installed on the hosted machine if we need to validate it is there.

When dealing with Mac OS it varies, found an issue on core repo here:

/usr/local/share/dotnet/dotnet --info

SO question notes following: https://stackoverflow.com/a/42309484

On macOS you could check .net core version by using below command.

ls /usr/local/share/dotnet/shared/Microsoft.NETCore.App/
On Ubuntu or Alpine:

ls /usr/share/dotnet/shared/Microsoft.NETCore.App/
It will list down the folder with installed version name.

@wsmelton - can you take a stab at this? I have to work on my PSConf Presentation and write Chapter 8 in the next few days and won't be available much until June 8.
