netstandard2.0 console app (classic framework)

[shiggan]

Create a netstandard2.0 console app compiled to classic framework; publish to GH

Will be a very thin Shim that ends up calling into the library which does all of the real-work(tm).

Build Tasks

• New project and hosting of the CLI librarys
• Update CI infrastructure to cross compile to 4.7.0 (or whatever version is netstandard2.0); and run automated tests on core lib.
• Package release build

Release Tasks

• Figure out how to push the release package to GH
