Configuracion de dominio para usar redis como un 2nd level cache para fluent nhibernate

dominio.cs

this.cadConexion = System.Configuration.ConfigurationManager.ConnectionStrings["Conexion"].ConnectionString;

            this.currentSession = Fluently
                .Configure()
                //.Database(SQLiteConfiguration.Standard.UsingFile("c:\\rfid.sqlite"))
                .Database(PostgreSQLConfiguration.PostgreSQL82.ConnectionString(this.cadConexion))
                //.Database(MsSqlConfiguration.MsSql2005.ConnectionString(this.cadConexion))
                // aca podemos usar el provider de nuestra preferencia
                .Cache(cache => cache.ProviderClass(typeof(NHibernate.Caches.Redis.RedisProvider).AssemblyQualifiedName).UseSecondLevelCache().UseQueryCache())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<DominioApp>())
                .ExposeConfiguration(BuildSchema)
                .BuildSessionFactory();
