'Newtonsoft' could not be found

问题

I pasted the code from http://www.codeproject.com/Tips/789481/Bridging-the-Gap-between-Linqpad-and-Visual-Studio into Visual Studio 15. It tells me that 'Newtonsoft' could not be found. I open the folder "\Microsoft Visual Studio 14.0\Common7\IDE\PrivateAssemblies" and found that the file Newtonsolft.Json.dll is already there. Could anyone tell me how to fixed problem?
