After running a clean solution and rebuild, my MVC 4 Web API project stops working. It\'s can\'t find Newtonsoft.Json.
I know that MS is using this as the default JS
You could try to install the SocialAuth.Net package with the ‑IgnoreDependencies flag, then installing the dependencies manually and making sure that you only install the latest version of Json.Net library.
Then at runtime the SocialAuth.Net package would respect the assembly redirect and load Json.Net (v4.5) instead of the old version.
