System.FileNotFoundException NewtonSoft.Json

I create a new netstandard 1.4 project - I add a from NuGet the Json package - all looks goos - I add one line of code to make sure the Json DLL gets loaded, JSon.Exception - I run the code and I get this

System.IO.FileNotFoundException occurred HResult=0x80070002 Message=Could not load file or assembly 'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.

I have tried this on several test projects - I have searched my drive and no DLL exists - I do not get a yellow warning on the NuGet package - it loads fine just no file comes down to my machine

Thanks

JK
