Start WPF Application in Console Application

Question

Is it possible to start WPF Application in Console mode?

public partial class App : Application
{
    public App()
    {
        InitializeComponent();
    }         


        

Answer 1

You could declare a Window and then start your app this way:

var application = new System.Windows.Application();
application.Run(new Window());

EDIT:

You seem a bit confused, so let me explain:

Say you have a program:

using System;

namespace ConsoleApplication
{
    class Program
    {
        [STAThread]
        static void Main(string[] args)
        {
            RunApplication();
        }

        private static void RunApplication()
        {
            var application = new System.Windows.Application();
            application.Run();
        }
    }
}

This will run a WPF application with no Window.

If, on the other hand, you pass a Window into application.Run(), you will get a WPF window. App should not derive from Window, since it should derive from Application.

Application.Run method either takes no arguments or a Window. It does not take Application. Therefore, if you want to start a previously created Application, as you have over there, you should do something like this:

private static void RunApplication()
{
    var application = new App();
    application.Run();  // add Window if you want a window.
}

Lastly, if you want to just use application.Run() and not have to pass a specific Window, just declare a starting Window in your Application XAML using StartupUri:
