Winforms are just console apps that show windows. You can direct your debug info to the console app.

As you can see in the below example there is a command that attaches the parent window then pumps info to it.

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace MyWinFormsApp
{
    static class Program
    {
        [DllImport( "kernel32.dll" )]
        static extern bool AttachConsole( int dwProcessId );
        private const int ATTACH_PARENT_PROCESS = -1;

        [STAThread]
        static void Main( string[] args )
        {
            // redirect console output to parent process;
            // must be before any calls to Console.WriteLine()
            AttachConsole( ATTACH_PARENT_PROCESS );

            // to demonstrate where the console output is going
            int argCount = args == null ? 0 : args.Length;
            Console.WriteLine( "nYou specified {0} arguments:", argCount );
            for (int i = 0; i < argCount; i++)
            {
                Console.WriteLine( "  {0}", args[i] );
            }

            // launch the WinForms application like normal
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault( false );
            Application.Run( new Form1() );
        }
    }
}
