While trying to migrate a project from 2019.2.21 to 2021.3.16, facing some issues with NewtonSoft...

So while migration, we are encountering some errors like mentioned below:


The type or namespace name ‘Newtonsoft’ could not be found (are you missing a using directive or an assembly reference?)


There are 5 errors with the same kind of message and we have tried all the solutions but aren’t able to solve it.

It’s a dll for json.

You can track it down online and get the right version and add it to a Plugins folder.

You can also install via nuget, there’s NugetForUnity that makes it easy, the nuget is NuGet Gallery | Newtonsoft.Json 13.0.3

It sounds like you’re probably hitting an issue with the DOTS version changes. Is one of the “all the solutions” you’ve tried looking into the DOTS package changes?
