I am nobie in C# .NET Core, and I would like to know if it is possible to display a TaskDialog in a Console type project?
With the C# .NET Framework I know it is possible to do this with MessageBox.

What I have tried:

Reading everything I can, on the internet and books on the subject ...

You could do it in the Framework? Possibly, but I doubt it. A console app is just an old black DOS command window. I don't think, though I never tried it, that it could show Dialogs.

A good idea to test and experiment before posting what you "doubt." See my post,

Sure thing bossy.

No, you can't display a dialog of any kind in a console app. That's why it's a console app.

Curiously though, you should be able to write a WinForms or WPF app without actually having to display a window, unless you choose to do so.

Vote of #1: absolutely wrong ... you can use MessageBox.Show, and you can create and show (modal, or non-modal) Forms in a console app. See example here.

However, just because you CAN, does not mean you should, or that it is a good idea !

changed vote to #3:

"Curiously though, you should be able to write a WinForms or WPF app without actually having to display a window, unless you choose to do so."

indeed, you can, using WinForms Application Context, but, why would you ?
I have not used Win Core.

Note: Think carefully before using a technique like this ... many users are socialized to expecting a Console App to not use MessageBox, or show Forms !

1) add using System.Windows.Forms; to your Console App.

1a) add a Form to your Console App Project. Put a TextBox and a Button on the Form.

2) example Console App
using System;
using System.Windows.Forms;

namespace ConsoleAppWithForm
    class Program
        static void Main(string[] args)
            // works

            Form1 f1 = new Form1();

            string data = null;

            // wire-up the Action delegate in Form1
            f1.TransferData = s => data = s;
            DialogResult dresult = f1.ShowDialog();


            Console.WriteLine($"result: {dresult} | value entered: {data}");

3) example Form
using System;
using System.Windows.Forms;

namespace ConsoleAppWithForm
    public partial class Form1 : Form
        public Form1()

        // event delegate for external consumers
        public Action<string> TransferData;

        private void button1_Click(object sender, EventArgs e)
            if (textBox1.Text != String.Empty && TransferData != null)
                this.DialogResult = DialogResult.OK;
                this.DialogResult = DialogResult.Cancel;

But strictly speaking that is not a Console app.

"that depends on what the meaning of 'is' is." Bill Clinton :)

the example shown was created as a Console app; the VS compiler thinks it's a Console app.

If you pain an elephant yellow that does not make it a banana. :))

That's like saying a baby born as a male is a boy, and according to the latest information available, we all know that's not true.

feed elephants bananas, and they are very happy ... but, they do not turn yellow.
