SOCKS5 Auth Implementation

[EugeneSunrise]

First of all, thanks for your work and support of this project❤️, and I look forward to upgrading and moving to a chrome runtime environment.

I use cefsharp for a tabbed browser and recently came across the question of adding a socks5 proxy with authorization. As we know chromium does not support socks5 + auth, but there is a workaround.
HttpToSocks5Proxy

This library allows you to connect over Socks5 proxies when using the .NET HttpClient.
It implements the IWebProxy interface and can therefore be used with all libraries that support HTTP/HTTPS proxies.

I easily added this library to my project and now I can use socks5 + auth proxy, I will attach the implementation code below

 var chromeProxy = profileToStart.Proxy.ToChromeProxy();
 await _context.SetProxy(chromeProxy);

 if (profileToStart.Proxy.IsProxyAuth)
 {
     _requestHandler.SetAuthCredentials(new ProxyAuthCredentials()
     {
         Login = profileToStart.Proxy.ProxyLogin,
         Password = profileToStart.Proxy.ProxyPassword
     });
 }

public ChromeProxy ToChromeProxy()
{
    switch (ProxyType)
    {
        case EProxyType.HTTP:
            return new ChromeProxy(ProxyType, ProxyAddress, ProxyPort);
        case EProxyType.SOCKS5:
            return new ChromeProxy(EProxyType.HTTP, "127.0.0.1",
                new HttpToSocks5Proxy(ProxyAddress, ProxyPort,
                ProxyLogin, ProxyPassword).InternalServerPort);
        default:
            throw new NotImplementedException();
    }
}

public class ChromeProxy
{
    private readonly EProxyType _proxyType;
    private readonly string ip;
    private readonly int port;

    public ChromeProxy(EProxyType proxyType, string ip, int port)
    {
        _proxyType = proxyType;
        this.ip = ip;
        this.port = port;
    }
    public virtual Dictionary<string, object> GetContextPreference()
    {
        return new Dictionary<string, object>() { { "mode", "fixed_servers" }, { "server", GetProxyString() } };
    }

    public virtual string GetProxyString()
    {
        return $"{_proxyType}://{ip}:{port}";
    }
}
