Visual Studio 2013 - adding same reference to foreground app and background task

Question

I am new to background task in windows store app.

I need to use the same library (Newtonsoft.json) in both foreground app and in my windows runtime component (background task).

Please how can I achieve this?

I installed it with nuget but I can use it only in my foreground app.

I have VS 2013 Express for Windows
