Error on user taks: The type or namespace name 'Linq' does not exist in the namespace 'Newtonsoft.Json'

Hi,

I'm trying to create a user task for getting a Gps from address. I tried this in a business process and all was working, now I tried puting this in a user task and I keep getting the following error:
The type or namespace name 'Linq' does not exist in the namespace 'Newtonsoft.Json' for this line: using Newtonsoft.Json.Linq;
Attached it the full user task code.
