Hello, I am starting up with hangfire for .NET core. Is the current release 1.6.13 supporting .NET core on Ubuntu? I started up the project with visual studio 2017 and get a few errors and warnings.

Do I have to remove a few projects to make it 100% compatible? Is there a bare minimum that does support it maybe without SQLServer integration.

On another note is there Redis Pro compatibly with core and Ubuntu currenlty?

I am including below the errors first and then the warnings I got from 2017.

## Errors

I have a Linux server running with 1.6.12 right now. 1.6.13 is not published on nuget yet, but there’s only a few minor changes between them, so it should be fine too.
