/*------------------------------------------------
 * Aggiunto fix come da link seguente:
 *
 * https://stackoverflow.com/questions/14033193/entity-framework-provider-type-could-not-be-loaded
 *
 * I solved this by adding an using stament on top of my DBContext class, like so:
 * using SqlProviderServices= System.Data.Entity.SqlServer.SqlProviderServices;
 *
