Example

using AmSoul.FPC1020;
using Microsoft.Web.WebView2.Core;
public MainWindow(){
  await webView.EnsureCoreWebView2Async(null);
  webView.Source = new Uri(textBox1.Text);
  LoggerListener listener = new(webView.CoreWebView2);
  webView.CoreWebView2.AddHostObjectToScript("fpc1020", new FPC1020(listener));
}
