The issue is with the connection string you are using.

Data Source=.;Initial Catalog=test;Integrated Security=SSPI

Check the SQL Server instance name running on your local.

Data Source=**.\YourInstanceName**;Initial Catalog=test;Integrated Security=SSPI

You can test your connection string validity by trying to add a connection in Server Explorer (Tools -> Connect to Server - VS2015).

Good luck
