How to install a serialization package(JSON or ProtoBuff) for HoloLens.

Hi,

I need an easy way to send data to my server from HoloLens.
Raw byte conversion is not scalable and NOT FUN.

I tried to install ProtoBuff(https://www.nuget.org/packages/Google.Protobuf) and JSON(https://www.nuget.org/packages/Newtonsoft.Json/) but I failed.

When I run

PM> Install-Package Google.Protobuf

I get

Attempting to gather dependency information for package 'Google.Protobuf.3.3.0' with respect to project 'HoloToolkit-Unity', targeting '.NETFramework,Version=v3.5,Profile=Unity Subset v3.5'

For JSON,

Do I need to build them from sources? Then how?
