Can Xamarain.Forms connection to MS SQL without WebServices? -- 用Xamarain連MS資料庫只能用WebServices嗎?

I am connection to SQLITE database in this way now:
(我現在是用這個方式連到SQL)

    public static FoodData Database_Food
    {
        get
        {

            if (database_Food == null)
            {
                database_Food = new FoodData(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "FoodSQLite_Test.db3"));
            }

            return database_Food;
        }


    }

I search on Internet catch the Informations always teach use WebServices to connection MS SQL，
Its really Xamarain.Forms can only direct connection to SQLITE database?
(我在網路上都是看到用WEBservice的方式以網路連到MS資料庫
是不是XAMARAIN只能直接連SQLTE?)
