By "framework" here, I mean the non-core legacy framework that is now at v 4.8. Not core 1.0-3.0 or versions 5 or 6.
For example, consider Microsoft.Identity.Protocols.dll version 5.2.4.0 vs. 6.7.1.0. Can these be associated with specific versions of the .net framework? Is there a general rule for such a correspondence?
Secondly, can I assume that any assembly that begins "System." is part of the framework? How about if it begins "Microsoft."? If the answer is "no", how can I know whether it is, or isnt? The question behind this question is that I want to know if I need to install a package for the assembly, vs letting the framework provide it.
