Answer 1

The following commands are available with .NET Core SDK 2.1 (v2.1.300):

To list all installed .NET Core SDKs use: dotnet --list-sdks

To list all installed .NET Core runtimes use dotnet --list-runtimes

(tested on Windows as of writing, 03 Jun 2018, and again on 23 Aug 2018)

Update as of 24 Oct 2018: Better option is probably now dotnet --info in a terminal or PowerShell window as already mentioned in other answers.
