Created Unassigned: is Freebase4net compatible in the application using WCF? [2]

i am using Wcf service(contract first approach) for my service layer. from businesslayer i am calling the freebase-search service.

below two things are happening:
1. if i call directly from the presentation layer to freebase-searchservice through businesslayer(not using wcf service in between ui & business layer) => then it works fine

2. when using WCF service , it throws exception like newtonsoft.json or one of it's assemblys not found.
while access the searchservice.read() .

please do the needful.
