Problem in System.Data.SqlClient when upgrading to 5 core aspnet

I updated all my project to aspnet 5 core because I was using the dnx vnext and apparently it worked everything right, but by conducting tests I noticed that some values did not come correct and to debug I realized that the parameter array SqlParameter is not picking up the values, for example if I have an array with 5 parameters and it contains parameters of type int it populates otherwise and I do not think it is some inconsistency of the lib System.Data.SqlClient, does anyone know anything about it? In the visual studio it is underlined, showing the following message:

Assuming assembly reference 'System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' matches 'System.Data.SqlClient, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35', you may need to supply runtime policy.

This is my project.json
