I'm self-learning using a book.. while working on methods the book introduces returning multiple values from a method. I've changed the code accordingly and installed related Microsoft NuGet package for tuples.. When I check the solution explorer, I can see that System.ValueTuple there and active.. But my project is not running accordingly as if I'd not installed the tuple package.. 

else if (division.IsChecked.HasValue && division.IsChecked.Value)
{
        int division, reminder;
        (division, reminder) = Divide(leftHandSide, rightHandSide);
                    result.Text = $" reminder ";
 }

....



        private (int, int) Divide(int leftHandSide, int rightHandSide)
        {
            expression.Text = $" / ";
            int division = leftHandSide / rightHandSide;
            int reminder = leftHandSide % rightHandSide;
            return (division, reminder);
        }



        private void showResult(int answer) => result.Text = answer.ToString();

    }
}

    "But my project is not running accordingly " Could you elaborate ? Does it throw an error ? or is something else? – Anu Viswan Sep 23 '19 at 11:28
