Having problems installing Newtonsoft.Json Nuget package in xamarin visual studio

Hey i had problems installing the newest Newtonsoft.Json package.

To be able to install it open the powershell as admin and perform:
1. start-job {Set-ExecutionPolicy Unrestricted } -RunAs32 | wait-job | Receive-Job
2. restart visual studio. (important :))
3. Install package
4. Change back for security reasons:
start-job {Set-ExecutionPolicy RemoteSigned } -RunAs32 | wait-job | Receive-Job
