Based on this documentation the code below should generate a message box, but all it does is print to the output tab:
How can I get it to produce the message box as advertised in the Microsoft docs?

Console.WriteLine("\n Assignment 6 - Asserts and Try/Catch.");
string fooString = null;
int fooInt = 0;
Debug.Assert(!String.IsNullOrEmpty(fooString), "Parameter must not be empty or null.");
Debug.Assert(fooInt > 0, "Parameter must be greater than zero.");
Here is the code from Form1.cs (tried with and without the Trace.Listeners code)
namespace Unit_6_WinForm
{
public partial class Form1 : Form
{

{
Trace.Listeners.Clear();
DefaultTraceListener defaultTraceListener = new DefaultTraceListener();
defaultTraceListener.AssertUiEnabled = true;
Trace.Listeners.Add(defaultTraceListener);
