After a lot of googling I've discovered that this method sets the $PublishDir

This should be documented better on the dotnet cli docs as it is not listed anywhere in the new .netcore 2.0, docs that I have come across atleast.

For anyone coming across this issue having similar problems a more reliable method would be to use msbuild and specify exacting properties.

dotnet msbuild /t:publish /p:PublishDir=dist/ /p:Configuration=Release
