C#

[SQLiteFunction(Name = "TOUPPER", Arguments = 1, FuncType = FunctionType.Scalar)]
    public class TOUPPER: SQLiteFunction
    {
        public override object Invoke(object[] args)
        {
            return args[0].ToString().ToUpper();
        }
    }       

    [SQLiteFunction(Name = "COLLATION_CASE_INSENSITIVE", FuncType = FunctionType.Collation)]
    class CollationCaseInsensitive : SQLiteFunction {
        public override int Compare(string param1, string param2) {
            return String.Compare(param1, param2, true);
        }
    }

C#

TOUPPER.RegisterFunction(typeof(TOUPPER));

solved in this way, but also mono c # 'using the library, here is how I need to do Android.Database.Sqlite.SQLiteDatabase
