Could not load type 'Newtonsoft.Json.JsonConvert.

Hello experts.

I m getting an error while i compiled the code.This DotNet Variable could not load.

NewtonSoftConvert@1000000001 : DotNet “‘Newtonsoft.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed’.Newtonsoft.Json.JsonConvert”;

Even i have DLL also,i think it comes with S/W also.

Kind regards.
