Newtonsoft Json include in crm plugin

HI,

I tried including NewtonSoft  Json dll in my crm plugin to parse Json via OData web service for purpose of update. When I am trying to deploy my plugin, it seems NewtonSoft dll does not get included. I tried many things Like ILMerge, using System.Json and all other ideas but non seems working. Does anyone has successfully achieved what I am trying to do. If yes, please help.
