using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp2
{
    internal static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp2
{
    internal static class Program
    {

        /// </summary>

            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}

line 18 Application.Run(new Form1()); ^^^^^ that didnt work

reflectronic•16mo ago

well, you changed the namsespace so it can't find new Form1() anymore. you moved it

Elmishh•16mo ago

reflectronic•16mo ago

you need to change the namespace of Program to be the same one as Form1

Elmishh•16mo ago

the original namespace wasnt Form1

reflectronic•16mo ago

when you do Application.Run(new Form1());, it's looking for a thing called Form1 in your program it's trying to look in the namespace WindowsFormsApp2 for Form1

Elmishh•16mo ago

im following a guide from microsoft 1 to 1 and its not working

reflectronic•16mo ago

but you moved it, presumably. it's in a different namespace now so you need to change namespace WindowsFormsApp2 to namespace HelloWorld that way it will find Form1 in HelloWorld, since that is where you put it
