Notes about .Net standard
I posted in Nov 2017 about .Net Framework, Core, and Standard.
A year later, we got the final version of .Net Standard, which was 2.1.
To close the loop on my original post (7 years late), I want to highlight that the last version to serve as a bridge between Framework and Core is .Net Standard 2.0.

This is the final version of the compatibility table hosted on the dotnet GitHub.
This offical .Net Standard page has a cool interactive table.
And this MS Dev Blog post has a section on what they were thinking when they separated Framework support from Standard.
