Answer 1

I know this is old, but I just ran into the same problem. My issue was that multiple projects in the solution used Newtonsoft.Json, but some were at different versions. I updated all of them to the most recent (9.0.1 as I type) and the problem went away.

Anyway... if anyone is still dealing with this, make sure to update the package in EVERY project in the solution.
