It is not impossible but why would you like to do so? Anyway to answer your question, I created a simple Windows App using C#, I just copied the code below for you,

C#

using System.Windows.Forms;

namespace GUI_Test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            AllocConsole();
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
        }

        private void button1_Click(object sender, EventArgs e)
        {
            System.Console.WriteLine("Hello World");
        }

        [System.Runtime.InteropServices.DllImport("kernel32.dll")]
        private static extern bool AllocConsole();
    }
}

Please ignore the naming convention, it is just a test app.

Hope it helps :)

There can be some reasons, for example, during development, to be removed later.
Now, what you're doing is too complex. The answer is really, really simple.
Please see my solution.

This, and the solution by Abhinav S are good when you want to build a DLL, not an EXE.

Not quite correct. What's "console application" It's quite easy to show both console and windows application. This method does work.
Please see my answer.

Here is the simplest way:

Create a regular Windows application, WPF or Forms. Go to Project properties and change application type to "Console Application". You application will become a console application and windows application at the same time.

Windows application and console application are not mutually exclusive. "Console application" really means "Show console". It does not mean "Don't create windows application". "Windows application" simply means "don't show console". By the way, if you use Console methods in non-console application, they will work (in a way)! Only without showing the results. But, for example, Console.Beep will always work.

Solution 3

See this[^]. This will help you actually display the console in a forms application.
