How to create a simple local web page using Windows C # forms

I am looking to create a simple web page using a C # Windows Forms application or a C # Console application.

Launching the application will begin hosting the webpage at:

http://localhost:3070/somepage

I read a bit about MSDN using endpoints , however, being self-taught, it makes no sense to me ...

In short, this program at startup will display some text on a web page in localhost: 3070.

Sorry for such an uncertain question, however, my hour of searching for a worthy textbook did not give any clear results ...

Thank you for your time!

HttpListener, , Listener.Prefixes.Add("http://+:3070/"), .

using System;
using System.Net;
using System.Text;

namespace TestServer
{
    class ServerMain
    {
        // To enable this so that it can be run in a non-administrator account:
        // Open an Administrator command prompt.
        // netsh http add urlacl http://+:8008/ user=Everyone listen=true

        const string Prefix = "http://+:3070/";
        static HttpListener Listener = null;
        static int RequestNumber = 0;
        static readonly DateTime StartupDate = DateTime.UtcNow;

        static void Main(string[] args)
        {
            if (!HttpListener.IsSupported)
            {
                Console.WriteLine("HttpListener is not supported on this platform.");
                return;
            }
            using (Listener = new HttpListener())
            {
                Listener.Prefixes.Add(Prefix);
                Listener.Start();
                // Begin waiting for requests.
                Listener.BeginGetContext(GetContextCallback, null);
                Console.WriteLine("Listening. Press Enter to stop.");
                Console.ReadLine();
                Listener.Stop();
            }
        }

        static void GetContextCallback(IAsyncResult ar)
        {
            int req = ++RequestNumber;

            // Get the context
            var context = Listener.EndGetContext(ar);

            // listen for the next request
            Listener.BeginGetContext(GetContextCallback, null);

            // get the request
            var NowTime = DateTime.UtcNow;

            Console.WriteLine("{0}: {1}", NowTime.ToString("R"), context.Request.RawUrl);

            var responseString = string.Format("<html><body>Your request, \"{0}\", was received at {1}.<br/>It is request #{2:N0} since {3}.",
                context.Request.RawUrl, NowTime.ToString("R"), req, StartupDate.ToString("R"));

            byte[] buffer = Encoding.UTF8.GetBytes(responseString);
            // and send it
            var response = context.Response;
            response.ContentType = "text/html";
            response.ContentLength64 = buffer.Length;
            response.StatusCode = 200;
            response.OutputStream.Write(buffer, 0, buffer.Length);
            response.OutputStream.Close();
        }
    }
}
