Question How to resolve conflicts (eg, Newtonsoft) in plugin?

    Since 9 out of 10 packages will use Newtonsoft, how the heck do plugin devs resolve dll dependencies?

    * Eg: Newtonsoft is everywhere in every package.
    * Eg: Unity <2019 doesn't include a bunch of core dlls, but 2020+ does.

    How to gracefully resoolve these as a plugin dev, where the current workaround is to get the end-user to scavenge through and delete 1 of them (which may cause issues for different versions).

    There is an official Newtonsoft-json package available through the Unity Package Manager. It's intended for Unity's internal usage, so it's not visible through the UPM UI.
    But you can install it by adding the dependency manually to the Packages/manifest.json file:
    Code (CSharp):
    1. "com.unity.nuget.newtonsoft-json": "3.0.2"

    If your Unity plugin is a UPM package, then you can add this dependency to the 'dependencies' section in the 'package.json' file of your package.
