hello i have some problems to implementing class library that hold the edmx entity

i have in my solution 2 project :
1)console application
2) class library ("modelsLayer")

in the class library i created an edmx entity using wizard

1) i add to the console app reference to "modelsLayer".
2)add the entity reference by dong browse to the dll at the "modelsLayer"
(to get the same version instead add entity framework from nuget)

3)and copy the connection section from "modelsLayer" into the console application config.

and then i got this exception :

Model1.ssdl(2,2) : error 0152: No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SqlClient'. Make sure the provider is registered in the 'entityFramework' section of the application config file

This is the class library app.config

 <?xml version="1.0" encoding="utf-8"?>
