Ideally you should be able to the proxy in options, but it doesn't seem to have been fixed yet: github.com/MicrosoftEdge/WebView2Feedback/issues/… - Poul Bak
Is the dialog that pops up a javascript dialog? - Poul Bak
not completely sure if its Javascript, It only pops up if I 1. Haven't connected to that internet today. or 2. I reconnected to it. - Redstone145

There are command-line options for proxy settings. You can set those options through AdditionalBrowserArguments property of an instance of CoreWebView2EnvironmentOptions and pass to CoreWebView2Environment.CreateAsync when creating the CoreWebView2.

For example:

WebView2 webView21 = new Microsoft.Web.WebView2.WinForms.WebView2();
private async void Form1_Load(object sender, EventArgs e)
{
    var options = new CoreWebView2EnvironmentOptions();
    options.AdditionalBrowserArguments = "--proxy-server=\"proxyhostname:8000\"";
    var env = await CoreWebView2Environment.CreateAsync(null, null, options);
    await webView21.EnsureCoreWebView2Async(env);

    webView21.Dock = DockStyle.Fill;
    this.Controls.Add(webView21);
    webView21.Source = new Uri("Https://stackoverflow.com");
}

Here are the options that you can use:

  • --no-proxy-server: Not to use proxy.
  • --proxy-auto-detect: Automatically detect proxy configuration.
  • --proxy-server=<scheme>=<uri>[:<port>][;...] | <uri>[:<port>] | "direct://": Use custom configurations.
  • --proxy-bypass-list=(<trailing_domain>|<ip-address>)[:<port>][;...]: Bypass any specified proxy for the specified semicolon-separated list of hosts.
  • --proxy-pac-url=<pac-file-url>: To use the PAC file at the specified URL.
