title: F#'s `netcore` class library shared by both `netframework` and `netcore` projects written in plain C#?
body: <p>So here we go: there are a lot of <code>Net Framework</code> projects, most of them are <code>&gt;= 4.7</code>, written in pure C#. And there are necessities to introduce new assemblies, written in F# for no matter what purposes, and <code>netcore</code> is desired. Is there any way to make new stuff referencable by <code>netframework</code> projects?</p>
