How I can fix this issue using this repo with WinForms app?

[zydjohnHotmail]

Hello:
I found your repo., it seems to be a good one, so I wanted to give it a try.
For using the console app by following the example from here:
https://github.com/mahdibland/Selenium-Proxy-Authentication.Chrome/blob/main/SeleniumProxyAuthentication.Sample/Program.cs
It works.

However, I want to use this repo in WinForms app. So have done the following:

1. Create a WinForms app project targeting .NET 6.0 (X64 CPU) on Windows 10 (Version 21H2). My IDE is Visual Studio 2022.

2. Install NUGET packages:
   PM> Install-Package Selenium.Support -Version 4.2.0
   PM> Install-Package Selenium.WebDriver -Version 4.2.0
   PM> Install-Package Selenium.WebDriver.ChromeDriver -Version 102.0.5005.6102
   PM> Install-Package SeleniumProxyAuthentication.Chrome -Version 2.1.1

3. The following is my C# code trying to do the same as console app.

using OpenQA.Selenium.Chrome;
using SeleniumProxyAuthentication;

namespace SeleniumProxy1Form
{
public partial class Form1 : Form
{

    private static readonly ChromeOptions Chrome_Options = new();

#pragma warning disable CA2211 // Non-constant fields should not be visible
public static ChromeDriver Proxy_Driver;
#pragma warning restore CA2211 // Non-constant fields should not be visible

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        Chrome_Options.AddProxyAuthenticationExtension(new Proxy(ProxyProtocols.HTTP, 		"proxy_server:proxy_port:proxy_username:proxy_password"));));
    }

    private async void BTNUKProxy_Click(object sender, EventArgs e)
    {
        Proxy_Driver = new(Chrome_Options)
        {
            Url = "http://ip-api.com/json/"
        };
        await Task.Delay(5000);
        Proxy_Driver.Navigate().GoToUrl("https://www.bing.com/");
        Console.Beep();
    }
}

}
But when I run my program, I always get this kind of error:
System.Reflection.TargetInvocationException
HResult=0x80131604
Message=Exception has been thrown by the target of an invocation.

By the way, the following C# code works for console app project.

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;

namespace SeleniumProxyAuthentication.Sample
{
public class Program
{
private static readonly ChromeOptions Chrome_Options = new();

    static void Main()
    {
        Chrome_Options.AddProxyAuthenticationExtension(new Proxy(ProxyProtocols.HTTP, 		"proxy_server:proxy_port:proxy_username:proxy_password"));));
        IWebDriver driver = new ChromeDriver(Chrome_Options);
        driver.Navigate().GoToUrl(new Uri("http://ip-api.com/json/"));
        Console.WriteLine("Done!");
        Console.Beep();
    }
}

}

I was thinking that my console project is using the json file, but I stop the console project, and change different proxy, or I even reboot my PC. But I still get the same error, but the console app project always works.
Please let me know how I can fix this issue, why it happens only for WinForms app?
Thanks,

Hi @zydjohnHotmail
I'm experiencing the same error,
I'm also using

options.AddProxyAuthenticationExtension(new SeleniumProxyAuthentication.Proxy(
        ProxyProtocols.HTTP,
        "ip:port:user:pass"));

This code run in a .net core application inside a loop with a 30 second interval
Did you manage to found an answer ?
