Utilizing `System.Data.SqlClient` with dotnet 1.0 Lambda Function AWS

I’ve added Sql.Data.Client, version 4.1.0 to my project.json file, restore then build out the function and deploy yet when I test I get a “FileNotFoundException” error with the accompanying “Could not load file or assembly 'System.Data.SqlClient, Version=, Culture= neutral, … The system cannot find the file specified.” Any suggestions from people that have gotten this to work before?
